Mechjeb maneuver planner. I've been using MechJeb mod successfully for some time now.
- Mechjeb maneuver planner Then, click 'Create and execute'. A warning may be stored in ErrorMessage during this process; so it may be useful to check its value. Reply thisisalili • Additional comment actions. 0 (tested with both versions) KSP version 1. I'm really looking forward to MechJeb for KSP 2. Sadly, none of the options Maneuver Planner seem to make sense for this. Stock game leaves you up to guessing, MechJeb allows you to fly by these numbers. I used mechjeb to solve for maneuvers, then I took some time and tried to analyse and understand what it was doing and why. // --- standard part parameters -- The MechJeb transfer planner relies on instantaneous velocity changes in the same way that the stock manoeuvre node system does. If your parking orbit is circular (which it needs to be or MechJeb will complain) then adjusting your departure angle is free (0 Using Ascent Guidance on MechJeb to get myself at 100km. I go for a 100kmx100kmx0º orbit. For example I am launching a supply vessel w MechJeb 2. I have 700+ hours of KSP under my belt and I use MechJeb to perform simple course corrections like fine tuning planetary (or satellitic) intercept. Going to launch pad Using Ascent Guidance on MechJeb to get myself at 100km Maneuver Planner I use "Hohmann transfer to target" after selecting the asteroid as target Maneuver Planner then says "target for Hohmann transfer must be in the same sphere of influence" So what exactly do I need to do to get near or try to land on If jumping from planet to planet, from a moon to another moon or going from a planet to a moon, Mechjeb is pretty much useless. I don't use Mechjeb to plan maneuvers, since mechjeb always seems to spaz on me when I try that. in A. 3. It IS KER with automation. KER for the info panels, because it's more customizable. When I told mechjeb to schedule a circularization burn, it scheduled a burn in 1h and 29 seconds, with 132. So I know the mechanics of how to use Mechjeb, but there's one persistent problem I have had for almost a year now. This library enables players to make automated low delta-v transfers between two planets or vessels in-game, either directly from their own kOS scripts or from the kOS console. If I have mechjeb create the node, I switch view to focus on the mun (or target planet), open the maneuver node editor, and tweak the node before executing the maneuver. After A. As for keyboard controlling maneuver nodes for fine-tuning, I really like that idea. Hit space and wait until MJ is done. Skip to content. Treat is as a learning exercise, try to understand what it does to get you where you want. Launch into orbit. It can also execute the nodes autonomously, and does so with a pretty high degree of precision, since it can time the With stock maneuver nodes you do your best to make the most efficient burn. Here's how mechjeb would do it: you would tell mechjeb how to do it. Oh, and I have KSP through Steam. You only need Mechjeb Maneuver Planner to achieve circularization + RCS to get even more precision. There is an Alarm Clock mod that does your first suggestion that I find indispensable. Every time I pull up the maneuver planner and try to use the Porkchop Selection to transfer to another planet, when I hit "Create Node," the game freezes and will then crash. The maneuver planner autopilot can be really nice as well. 33 km orbit for my deployment vessel; (ii) establishing a 2/3 resonant orbit for my deployment vessel after deploying the first satellite; and (iii) circularizing the last two satellites on their final 2863. 2 and 2. I guess I always just did a hohmann transfer Reply Numinak • Additional comment actions. Forscience works, but no mechjeb : Skip to content. If you're using one of the really recent builds of MechJeb then I believe the advanced How to do get mechjeb maneuver planner to activate the engine I want it to use and not just use the rcs? When I tell maneuver planner to execute a maneuver it will warp to execution and then only use rcs instead of activating the engine Share Add a Comment. This video wil Rendezvous planner: Helps with rendezvous, but you can rendezvous easily using only tools in the Maneuver Planner section. However, it seems I can only specify the periapsis I need but not the inclination when I make planet transfer nodes or Multiple Gravity Assist Trajectory Planner for KSP By Krafpy. I would also like to see an advanced maneuver planner that helps you plan advanced maneuvers like gravity assists which require specific orbital The benefit of this is that MechJeb will be much more accurate at executing the node since the thrust is so low. 11. SMARTASS seems to be slightly better tuned than stock SAS, which is nice. I do this for about 1200m/s, and plan it out for about 200 days: Execute the operation and create appropriate maneuver nodes. Click "create node" 6. These match up fairly well to the data that the web tool gives you. 20 GameData format MechJeb now has the ability to execute Principia Maneuver Nodes. I do use it to execute maneuvers though, especially if they're going to take longer than 2 minutes. Save some space if you use BOTH mods and use MJ. Learn how to use MechJeb, a mod for Kerbal Space Program, to launch and orbit your rockets with ease. Skip to main content. There is only one button at the bottom of the There's a Maneuver Planner that gives you all kinds of fun options that basically creates or modifies existing maneuvers to do all sorts of things. Mechkeb is working This tutorial shows how to use the new Maneuver Tool and the Graphical Maneuver Editor to get into orbit and return from Kerbin's moon Minmus. The issue is that when I use mechjeb to execute the maneuver, the burn starts way before the principia maneuver planner says to ignite the engines and it never shuts them off until all fuel is spent. 0 Getting Started. Sign in Product Actions. I just started a new career a few days ago. io/ksp/. I've read somewhere that KSP maneuver-nodes assume 0-time burns, so they are not 100% precise, even if we use MechJeb or do it by hand. 5. 01. 6x Kerbin rescale :) it doesn't have that problem as most planets are on the ecliptic The orbital plane of the "planner/command" craft doesn't matter so much as you can launch the payload craft into the proper inclination for transfer a week before the window and recalculate the maneuver with the MechJeb porkchop planner. Both of these problems could be solved with a kOS script, with one bit of code to execute a gradual and predictable gravity turn, and one bit using the built-in node() function to create maneuver nodes. Set orbit to 100 km. Don't execute the maneuver! Just create it. These are best done at high transition nodes (usually half way between LKO and Minmus). Mechkeb is working But I always check MechJeb's Maneuver Planner and it is always late by 2-5 days. So, if you're launching 3 satellites, use 2/3; 4 satellites, 3/4; etc. both are available on CKAN. Check that the predicted pereapsis is where you want it (Suggested: press F5 to quick save) 7. Maybe like this? Step: 1-10-100-1000 Time: + - Prograde: + - Normal: + - Radial: + - Snap to: Per Galera, estou fazendo tutoriais de MJ com os recursos que eu uso, não sei 100% mas com o que sei já dá pra vcs fazerem muitas coisas, espero que gostem. Expand user menu Open settings menu. When i try to go from kerbin to duna, eve or another planet, mech jeb seems to plan a good maneuver mode but, i have 1, 2 or more years to reach the node. If you want MJ to auto-warp through Qualified yes. Seriously, spacecraft have been using computers to execute burns forever MechJeb 2 (When I use the MechJeb maneuver planner, I still can't get an encounter) MechJeb 2 Embedded EVE I have Breaking Ground and Making History. Regex wrote this plugin to fulfill a singular request he had since he started seriously playing this game: the ability to see the ejection angle of a maneuver node. It open MechJeb's maneuver planner, "Advanced Transfer to Another Planet" If you don't see a colorful picture right away, press "Reset". In doing so, I'm using the MechJeb manoeuvre planner for three things: (i) circularizing a 2863. Maneuver planner sometimes generates quite wild things for simple maneuvers. It includes Flight Plan, Maneuver Node Controller, K2-D2, Micro Hi there, i have unlocked Advanced Flight Control but the maneuver planner is not available on my mechjeb; why is that? Execute the operation and create appropriate maneuver nodes. MechJeb > maneuver planner > advanced transfer mode, only works for in-flight vessels but does so fairly well, with an occasional nonsensical node (like going from Kerbin to Eve by going solar retrograde) if you try to force a transfer outside the normal parameters. g: 400-600 km. Mechjeb drawer>ascent guidance. After unlocking mechjeb and then upgrading to the next level (the technology that costs 90 research to unlock) and upgrading the tracking station 1 time (the upgrade that costs 150000 credits IIRC), if I click on my orbit no new maneuver node appears. I've searched youtube but haven't found anything dealing with this specific MechJeb tool. Let launcher orbit once, and a few minutes before Ap, detach one The first step is to create a prograde maneuver using Principia's flight planner in Kerbin's non-rotating reference frame. Wait until MJ is done After you have a stable orbit, close Ascent Guidance and open the Maneuver Planner from the MechJeb menu. I had a feeling title = MechJeb Features- Maneuver & Translatron manufacturer = Anatid Robotics description = Unlocks the following MechJeb windows: Maneuver Planner, Translatron, Warp Helper, Attitude Adjustment, Thrust Window, RCS Balancer. But there is one piece of its user interface that is puzzling me. MechJeb's Maneuver Node Editor does make eyeballing it more accurate, and of course executing the nodes with Mechjeb improves accuracy and eliminates tedium, but I'd like even moar speed! For example, in placing a Mun satellite I came in with a larger orbit. Planned Hohmann transfer to Mun. This has happened multiple times, but NOT everytime. Delta-v numbers shown in the staging stack during flight dynamically reflect the current flight state. Then Step 4: plan your maneuver. 7, MJ#883 With heavy vessels (just tested with a vessel having 590 tons wet mass before LKO circularization burn), MJ often can't execute nodes as it is unable (unwilling?) to change orientation to execute next maneuver. I grasped many of the tools this mod gives, but ascent guidance is NOT one of them. 87, K2-D2V0. There's also a Rendezvous Planner which is a little less automated. I don't want to create a 1000th maneuver to transfer to Mun or Duna or to rendezvous with a station on LKO. Actually the node can be removed, but any Yeah, I can relate to that. I used MechJeb to time the transfer window and it seemed to do so nicely. EDIT 2-10-20: I have been able to get an encounter (with the Mun) before. See different methods, Make a launcher rocket with N>=3 detachable satellites. When you leave thhe atmosphere press T if you haven't already and follow the maneuver guidance. Activate (Ascent Guidance and) Maneuver Planner in the dropdown menu. This is why you should adjust the maneuver node before the transfer burn. Any advice? Greets, Malakai030 If you don't set the periapsis change maneuver at apoapsis, it will automatically do the burn that requires the least amount of delta-v, which is bound to change your apoapsis too. I think it's the best of both worlds and the evolution of any game that involves research and tech - the new tech should make the repetetive tasks simpler so you can focus on bigger picture stuff. The other problem is that your launch is going to be pretty variable, so you won't be able to plan a maneuver with a lot of precision. Mechjeb will also say that you are already orbiting eve if you have a maneuver already planned out to get yourself there. Mod List - 2024. Automate any workflow Packages. Use MJ to set apoapsis to 2 863. If your ship has low TWR, you want to park into an intermediate orbit at e. Image showing planned maneuver node causing impact with the surface. TargetInvocationException: Exception has been thrown by the target of an invocation. 6. Describe the bug krpc. ---> System. When I open the editor, it has the information for I keep trying to use the planner, but it keeps saying "Blank cannot be lower than the burn [insert altitude here]" Where am i going wrong? I followed a guide but that didnt help at all I followed a guide but that didnt help at all Invoke the MechJeb main interface, the one with Ascent Guidance, utilities, settings, Rendezvous Planner, Rendezvous Autopilot, and you click on Maneuver Planner (?), then you change the maneuver dropdown to Advanced Transfer to Another Planet, make sure that lowest dV is checked, and the window ought to build itself. Then, click ‘Create and execute’. biz/ and helps to explain how the information is used, In-game Mods like Mechjeb 2 with it's Maneuver Planner or Astrogator help with creating and executing transfers. Your method obviously works but I do like the ease and automation of this option Reply reply gjulianm • Just a tip when using the Hohmann transfer from MJ: Always I'm trying to do a hohmann transfer to the moon with mechjeb maneuver planner but it doesn't want to work It create the node but the deltav it ask doesn't seem to be enough because every time it use the whole deltav bar (the green one) but it doesn't complete the full maneuver and put my ship in the wanted trajectory Please help I lost 2 hour trying to go the the moon without * Maneuver planner is beyond useful. 0-943, Keeping this brief because yes, we're kinda off-topic now: Well, there's BetterBurnTime. Usually you want to move the whole node along your parking orbit a little bit to adjust your departure angle and thus your encounter distance. For example I use it for getting two rockets to rendezvous with each other; everything works fine until getting them closer together. I also find some versions tend to freak out when there are more than one in sequence. There are no Once you know what you're doing, I recommend using MechJeb to avoid the tedium of minor course corrections. It provides a scriptable alternative to existing tools, such as the excellent web based Launch Window Planner or the snazzy MechJeb Maneuver Planner. Both trajectories should be similar though near the maneuver, the N-body trajectory from principia is the accurate one. Tried to update MJ, but that didn't help. Changing the inclination dont help. Then at that point, redo the porkchop plot to get a new maneuver node, and then The "match inclination at AN/DN" action in the maneuver planner can set that up for you. The launch windows it comes up with typically fall a little earlier that those Just a tip, Maneuver Planner has an option for "Hohmann transfer to target" or something like that. With Flight Plan and K2-D2 you MechJeb has a bunch of insanely complex code in its innards for completely replacing stock SAS; it's manually computing rotational momentum tensors, the whole nine yards. The maneuver planner should cover most of your needs, but has separate buttons to plan and execute nodes. Reply reply It even auto warps me to the node, stops to ready for the burn, and I just slip by. This seems kinda expensive in terms of DV and you have to do two maneuvers. If you try and launch into Moho's inclination you'll be at it forever. 12 save and I'm having issues with its 'Ascent Guidance' option. 0. cs & coursecorrection. MechJeb can also make a number of space maneuvers for you, including launch, transfer, and landing. For some reason, after the eve escape I no longer see my planned orbit. It Plan a purely prograde burn with the given Δv Adjust until you get a close encounter with the target planet. This maximizes your Oberth Effect boost. Why is Rendezvous Autopilot broken for me? Lots of people will tell you not to use Mechjeb till you can do everything, but I have a different view. On the right side of the screen, there is a new maneuver tool. In some cases I use MechJeb to set up the initial maneuver and then tweak a bit. Step 3: Match Moho's inclination either through mechjeb' maneuver node planner or with the help of the KSP wiki. For example, you just launched a craft from Kerbin and have it on a suborbital trajectory, in the Maneuver Planner you can then select "Circularize", choose the option "At the next Apoapsis", and it will automatically create a node I have Flight Plan V0. Both inertially-fixed and tracking manœuvres are supported. Trip planner – the trip planner occasionally displays inaccurate delta-v numbers for some destinations. I tested this feature and it works, the problem is that MJ start staging my rockets all the time, even when I'm controlling it!I was thinking of a feature that had this checkbox inside the window of the 'Maneuver Planner' or 'Maneuver Node Editor', and MJ just staging when performing the action. There is NO FUNCTION of KER that Mechjeb cannot do. It takes the place of several mods for me, maneuver planners, flight computers, say i have an hour long burn I can let mj manage it while I go make dinner, landing prediction ect ect. It helps you to visualise the cost of a planetary transfer and when the most efficient burn is in the future. When we have wonderful tools like alexmun's Launch Window Planner allowing us to plan our tr So I've just gotten mechjeb on my 1. Once in game, even with mechjeb parts powered up, the maneuver planner window would not open. This will be addressed in a future update. In limited time mode, MechJeb picks the best time and burn in the time constraint you specify. KILLROT works like the basic SAS hold button, it tries to maintain the current orientation and stops any rotational movement. Too often do I forget I need to stage in-between and end up having to quickload or revert. ) In the log i get this several times (KSP 1. Looks like other utilities in Mechjeb to throttle me up (ex. 5. Edited December 26, 2014 by SpaceLaunchSystem How do I use MechJeb maneuver planner? After you have a stable orbit, close Ascent Guidance and open the Maneuver Planner from the MechJeb menu. You're better off setting up the maneuver node manually and just use the Maneuver Node Editor of MJ to fine tune it. Log In / Sign Up; Advertise on Reddit; Shop If you want autopilot then yes, but if your just looking for information to help you orbit and land I think the last patch pretty much added all that to the new orbit windows and maneuver planner. When I turn off the autopilot and press shift, I throttle just fine. Rendezvous Autopilot can be a time-saver *if* you and your target is in more or less the same orbit Maneuver Planner -> Advanced Transfer to Another Planet -> Set planet as target -> Create and Execute That colorful plot represents the balance between dV (color), time to departure, and travel time. When using a certain feature from MJ, not only does the job for you but also shows you how it achieves the result by displaying the maneuver node on the map and even the information status of a certain action in some feature panels. Starting out in a Low Kerbin Orbit this demo shows how to use Flight Plan, Maneuver Node Controller, and K2-D2 to perform the following actions and maneuvers needed for a trip to distant and dusty Dres. If you've got FAR, change the curve to 100%. I can't seem to find the 2. Once that's done, you set the planet you want to go to as a target, then in the Maneuver Planner find "Transfer to another planet". , and the custom window editor (to customize an info window so you don't need to open and close multiple during a mission). Similar to the 'Ascend Guidance' mode! Thanks. 4. (Don't forget to tell MechJeb to title = MechJeb Features- Maneuver & Translatron manufacturer = Anatid Robotics description = Unlocks the following MechJeb windows: Maneuver Planner, Translatron, Warp Helper, Attitude Adjustment, Thrust Window, RCS Balancer. Thrust turn off when I speed up warp while mechjeb Maneuver Planner working. NullReferenceException: Object reference not set to I like this game for designing the rockets and designing the flight plans. " Use the Maneuver Editor to fine tune it a bit, then hit "Execute" in the planner and you're on your way. Be careful when using, mechjeb seems to ignore the max speeds I set and accelerate until my rover flips out and explodes. I like MechJeb for rendezvous. In this case you have two maneuver options: On the far side of Kerbin from KSC, burn prograde to get an AP around 120km right around the west coast of the continent where KSC is, then do a deorbit at the AP such that your trajectory lands you at KSC. It starts the burn waaay to late so I end up falling back down into If you're looking for a single KSP2 mod that can do everything that MechJeb did (and still does!) in KSP1, well Flight Plan brings you many of the features and capabilities you might remember from MechJebs Maneuver Planner capability. Curious about this. Usually it only takes a few dV or moving the node by a few Use maneuver planner firstHohmann transfer and then follow that up with “match velocities at closest encounter”. Added a "Create and execute" button to the maneuver planner; Fixed RCS Avaiable Torque; Hopefully fixed throttle sputtering near end of gravity turn; Split "Rendezvous Guidance" into separate Autopilot and Planner windows; Changed attitude controller PID parameters to save to Type; Changed CFG for 0. 7 (via CKAN) with a bunch of other mods (mod_list. Sometimes, with MP engaged, I can manually move the spacecraft to the correct attitude and the main burn will occur. I have unlocked the research tree necessary for that feature. Started with Maneuver Planner - setting new periapsis and The MechJeb transfer planner relies on instantaneous velocity changes in the same way that the stock manoeuvre node system does. etc. I'll set up nodes by I've already wrote to you some posts ago that the "Ascent Guidance module" and all the others modules included "Maneuver Planner" and almost all the features are available since the 1st launch by using "Scripting Module" and I quote: [well ok I found what is needed for a fully functional autopilot ascent guidance. This is the altitude it will attempt to hit, but it never really does. cs (obviously other changes were made to other files yeah that's why I use kOS, although I will use mechjeb autopilot for rendezvous because the maneuver planner is non intuitive for scheduling burns more than a few orbits after your current one. Host and manage packages Security. Once in orbit, with Duna targeted, I opened the Maneuver Planner and selected advanced transfer to another planet. The craft has enough fuel to do the TLI and then spare fuel to do the capture burn. As if I was flying without one hand. Note that these are custom maneuver nodes and not ones created by MechJeb itself, although even these I would say MechJeb starts the burn too late. Going to launch pad Using Ascent Guidance on MechJeb to get myself at 100km Maneuver Planner I use "Hohmann transfer to target" after selecting the asteroid as target Maneuver Planner then says "target for Any chance of posting a screenshot on the pad with the mechjeb menu open, alongside the maneuver planner. But after a few seconds the dV displayed starts increasing faster and faster, and refreshing the orbit rapresentation I can se that the node moves in time. 0-943, I'm trying to make my way to Duna. Those nodes are super fiddly to work with and, generally speaking, I can just tell MechJeb to plot a course and the course is good enough to get the job done. In that window you can select a number of different maneuvers to create. MechJeb Lite is a collection of mods for Kerbal Space Program 2 that help you plan and execute maneuvers in space. Reflection. 2. There's a reason that Principia comes with its own flight planner; if you Using Mechjeb, I can use the pork chop plot to plan a flyby, but I can't seem to find a good way to plan the return. 62 m/s in the prograde direction, 0. Im in a good orbit, 100km with eccentricity 0 and inclination 0. Find and fix vulnerabilities Actions. If you have MechJeb, it can do steps (4) and (5) for you; use the "Advanced transfer to another planet" in the maneuver planner, and click The MechJeb 'Landing Guidance' pop-up showed as "Coasting to deceleration burn", but the burn was never performed, regardless of how fast, or slow, I was going. Quote; Link to comment Share on Mechjeb's "porkchop selection" in the "advanced transfer" window of the maneuver planner should be close enough to what you are looking for. Please help as when using the maneuver planner the same thing happens! Thanks, mbkgit Thanks, mbkgit During the ascent stage, Mechjeb creates a node and upon arrival, says its circularizing but doesn't increase the throttle. So, i archived my save and GameData (there are some mods needed to use the save) - there is a quicksave from the craft with this strange behaviour, it has a node which can not be executed. - of course the Tracking Station and Mission Control for Im using the engineering tech tree and I cant find the maneuver planner for mechjeb, ive looked throught the tree three times and its not there. Oh man I'm confused on MechJeb! I don't know what most of it is or does. 1 Description According to the Maneuver Planner, the resonant orbit operation should change my orbital period to a specified resonant value. Start burning so that when you reach you node it will be half done. You should get a "Execute next Principia node" button in the Maneuver Planner + Node Editor. 17. There's a reason that Principia comes with its own flight planner; if you What version of MechJeb and KSP are you using? With the new update things aren't working great with unupdated MechJeb I been using Principia for a while now, but I don't think mechjeb maneuver planner will execute a maneuver that it did not create. It does it so quickly no matter where the vessel you're meeting up with is in the orbit. I went through the GitHub files and found there was a version history and a few changes to the decelerationburn. It starts the burn waaay to late so I end up falling back down into The maneuver node planner is perhaps the one you will use the most. Close Ascent Guidance. Gravity assists are an efficient method to save fuel in interplanetary missions. Set orbit to like 200km) 3. Wait until you're a day When i try to go from kerbin to duna, eve or another planet, mech jeb seems to plan a good maneuver mode but, i have 1, 2 or more years to reach the node. The only autopilot function in MechJeb I use regularly (and even that, not always) is Ascent Guidance, because it flies more efficient ascents than I do, and I don't like wasting Delta-V. If you have the moon selected as your target and use that option, you tend to get a much closer and nicer encounter. Im fairly new to the modded world and i saw that many use Mechjeb to automatize launches, orbits and whatsoever. I don't know what assumptions it makes about your destination (flyby? orbit? If the latter, what inclination?), but I do know that it starts it's calculation with the actual orbit you are in. In the secondary Maneuver window you’ll see a few more options to “plot” the maneuver nodes. I've been using MechJeb mod successfully for some time now. Once ship is intercepted into the planet's SOI, create and execute a "circularize" node. Toggle navigation. Also, The mechjeb pod doesnt show up in the VAB after i research it, which also happened with another pack of mods i was using. Set a target, press go. 3 Description Time warp doesn't activate when selected in Maneuver Planner Replication Case Build or choose a spaceship Reach orbit Design any maneuver in Maneuver Planner Activate Autowarp KSP. If you want the dev version of MechJeb then : open CKAN settings (Settings => CKAN Settings) press the New button select the MechJeb-dev line, click OK and exit the options. Even KSP can show you the results of a gravity assist maneuver though, passing into and out of a moon or planet's SOI, if your patched conics setting isn't too low. Input desired altitude. Instant dev environments Copilot. Once you're well en route, use Fine tune closest approach. 33 km orbit after deployment on their next apoapsis. With the mods I have, or with the help of mods I don't, is it possible to plan a route to launch and intercept a target right after launch? The maneuver node planner is perhaps the one you will use the most. Easiest way to do a circularisation burn is to set up a maneuver node, either manually or by using the maneuver planner. txt; Image showing Orbit around Kerbin. 3 or later) is installed, then a MNC Icon botton will be presented in the lower right part of the GUI (between the Make Node button and the K2D2 button if present). Rover Autopilot: Will basically press the gas for you once your rover is on the ground. kRPC. Unfortunately the maneuver planner from my MechJeb doesn't work like I want it to. refresh select "Mechjeb2 - DEV RELEASE" in the list and then "Go to Change" to install Common problems. It'll get you closer than the transfer though. When I try to hohmann transfer to an object in LKO, MJ only plans one node. The code technically has nothing to do with PVG, but this is probably a good place to document it for Principia players. When I first began learning the game a lot of things didn't 'click' until i saw mechjeb set up trajectories with my custom built ship. You have to be in an equilateral orbit with very little inclination for it to work well though. Being able to create the maneuver node myself and then just press a button and let A workaround is to use the Maneuver Planer (Change plane to plane of target, bimpulsive hohmann transfer, aleing speed at closest approach. Switching Description; Comments (26) Files; Images; Relations; This tool helps you to plan efficient planetary burns. So I went ahead and used Mechjeb to put me in a circularized orbit around Eve, this is where the issue Before I get flamed - yes, I docked with another ship in orbit by hand, landed on both moons, orbited the sun and came back, positioned several satellites where required by contracts etc. 9. Why would this be? It always sets up a maneuver node significantly later than all the other recommendations. Go to "Hohmann Transfer to Target. Try deleting your maneuver, change the drop down to Hohmann transfer, and hit create and execute. That makes me think that MechJeb takes its time adjusting maneuvers and that can be a bit counter-productive, since we should be using the max available thrust. log A workaround is to use the Maneuver Planer (Change plane to plane of target, bimpulsive hohmann transfer, aleing speed at closest approach. Play around with maneuver nodes, and remember you can grab them and scrub This is why you should adjust the maneuver node before the transfer burn. Go to map and set Mun as target. Not sure if that helps, but thought I'd add it anyways. When I got into the pull of Eve my node showed a path through the core of Eve (meaning I would crash instead of escaping). 14. Press "execute next node" Unfortunately I accidentally kicked off my game start script which wiped out the log but I recall the many mechjeb messages on the loading screen were related to not being able to find a part or a module. Is there way to make it work while mechjeb Maneuver Planner make his work? Could you describe this issue in more detail? Exactly how can I reproduce? What relevant mods do you have installed besides mechjeb ? Edited June 24, 2020 by FreeThinker. Yet another maneuver node editor. Quote; Link to comment Share on The patched conic trajectory is also not N-body and quickly becomes a pile of lies. When I generate the node everything is ok. With this said, i only use mechjeb because i need the info and refuse the tedium of burn management and thats that. Select "fine tune closest approach to target" under Maneuver Planner and create and execute node. // --- standard part parameters -- I would like MechJeb to plan this initial burn for me. executing a maneuver node, 2. You can use it to have the game plot the maneuver for you. It was especially helpful with helping If you're looking for a single KSP2 mod that can do everything that MechJeb did (and still does!) in KSP1, well Flight Plan brings you many of the features and capabilities you might remember from MechJebs Maneuver Planner capability. Tap shift then X to see how long your burn will take. Being able to create the maneuver node myself and then just press a button and let It acts as both an excellent way of getting to know each feature of mechjeb and also encourages the player to at least understand basic orbit mechanics first. Instead, it remains open only until the next time I exit Flight mode, and then must be reopened the next time I enter Flight mode, no matter what craft or vessel is the Mechjeb has them as well, but I primarily reserve MJ for the basic piloting features. Toggle through the options until you find "adjust pereapsis" 3. 86 m/s in the normal direction, which when you use the 3d pythagorean theorem, d = sqrt(a^2 + b^2 + c^2), you get 132. Clicking "Lowest dV" will automatically choose the most efficient transfer window, but there are sometimes sooner windows with only slightly more I'm a fairly experienced KSP player and MechJeb user. I use a normal rocket with plenty energy and multiple stage to get to minmus, and if I'm piloting it there's no problem, but when I use the ascent guidance it starts being a bother. Since the last KSP update I'm encountering some problems with the Maneuver Planer. github. My mechjeb is the dev version and both, mechjeb and KSP are up to date. Its the best utility of the whole mod. Don't try to think that you can use MechJeb's maneuver node editor instead of Principia's planner, it isn't wired up that way. It tries to do it in last second so your main engine gives it a spin with dying energy but afterwords there is nothing to stop rotating. Reply reply More replies I've already wrote to you some posts ago that the "Ascent Guidance module" and all the others modules included "Maneuver Planner" and almost all the features are available since the 1st launch by using "Scripting Module" and I quote: [well ok I found what is needed for a fully functional autopilot ascent guidance. Eve's So I've just gotten mechjeb on my 1. There are two modes for transfer to another planet. With Flight Plan and K2-D2 you Qualified yes. Once you unlock MechJeb in the tech tree, you only get the basic features up-front. If the transfer doesn't work, probably just do it yourself. * The informational panels are must-haves. 6 m/s total since the prograde CKAN has all the release of MechJeb. What I would recommend is to create the node, but don't execute it. Abs. This guide covers the settings, profiles, and tips for ascent guidance, and provides You know the rainbow-colored transfer map that appears in MechJeb2? You can left-click and drag to "zoom into" an area from now to a couple-years away and then recalculate the After you have a stable orbit, close Ascent Guidance and open the Maneuver Planner from the MechJeb menu. On the Maneuver Planner, when I select the advanced transfer to another planet option, I get this colorful display below, that apparently can be used to select a maneuver node. Idk why it Wont work but if you want to „force” it to work then after clicking on land somewhere or land at target, create any manouver in planner and then delete it, that should make mechjeb do autoland just fine. Use Flight Plan to easily select a distant celestial body ; Use Flight Plan to make a maneuver nodes; Use Flight Plan to have K2-D2 perform a precision Once in orbit, use the maneuver planner to get Ap = Pe. Open "maneuver planner" 2. 9, MechJeb 2- DEV-RELEASE 2. has set you in a stable I use mechjeb or the stock maneuver node planner to generate the kerbin ejection burn. Sort by: Best Been using this mod for a while, wondering if you could add the Auto-stage feature to the Maneuver planner. Hit the "Create Node and Execute" button. After you enter the To get into the orbit I'll place a maneuver node at the new PE; making the orbit circular is simply adding retrograde until the PE and AE values are near the same value, but if you wanna, you can select "Circularize" on the Maneuver Planner of MechJeb for that node at the PE and it'll work it out for you. When I play without Smart A. 90, Node Manager V0. Technically with MechJeb you never need to learn them. 7. Instead of making a direct transfer from the departure planet to the destination one, we can perform fly-by's of intermediate planets to let their gravitational pull deviate our inital trajectory, without the need to burn fuel. It's a huge step up from the old Hohmann transfer function, though it does use a stochastic solver (it does a random sampling of trajectories, finds the best cluster, then does a detailed search of that cluster for the best candidate) so you may get different results on subsequent runs. If you do this, don't forget to re-click the "Active Engine" button in the maneuver planner's UI so it will take this change into account. All delta-v numbers in the VAB use vacuum specific impulse numbers, which affects their accuracy. MechJeb 0. Plus. Flight Plan's core strength is as an aid to help with setting up maneuver nodes to get you where you want to go. This always worries me BUT, if I make the Mun my target and I go for a 100kmx100kmx0º orbit. In other cases I just use it to get a visual on where my maneuver should be and then set up my I get my craft into orbit, circularize with an inclination of zero, and an altitude of about 650km and use Maneuver Planner's transfer to another planet option. If your parking orbit is circular (which it needs to be or MechJeb will complain) then adjusting your departure angle is free (0 Probably no one thinks of it this way, but I used to use Mechjeb as a sort of tutorial in the earlier game. I watch the T- come and go with no throttling. Accent guidance and After you place the Mechjeb computer on your rocket/spacecraft a dropdown box becomes available where you can select modules. The MechJeb menu is not showing Okay so this is what I'm doing. What Mechjeb tries to do is once it has reached apoapsis, it will hold prograde until coast to circularization. Which ones I'm using vary based on what I'm doing but I With stock maneuver nodes you do your best to make the most efficient burn. In other cases I just use it to get a visual on where my maneuver should be and then set up my own on whichever orbit best fits my schedule. So, the short answer for "how can I get automated maneuver execution like MechJeb" boils down to, basically, "use MechJeb. In the A forum thread where users ask and share tips on how to use MechJeb2 autopilot for launch, orbit, rendezvous and landing in Kerbal Space Program. It also allows me I downloaded MechJeb and Chatterer. I normally try and go for a 85-100km orbit for anything and it does that fine too until it makes the maneuver node. Pressing the MNC button will bring up the Maneuver Node Controller mod for easy finetuning of your Flight Plan generated maneuver node. This website has a fairly good overview https://ksp. Probably no one thinks of it this way, but I used to use Mechjeb as a sort of tutorial in the earlier game. Automate any workflow MechJeb shows you a lot of information, both design and flight parameters that the stock game won't tell you. Select Duna and use the manuever node planner thing Transfer to another planet. For example, you just launched a craft from Kerbin and have it on a suborbital trajectory, in the Maneuver Planner you can then select "Circularize", choose the option "At the next Apoapsis", and it will automatically create a node It even auto warps me to the node, stops to ready for the burn, and I just slip by. types. Open Maneuver Planner. It's not quite what you asked for (won't plan or execute maneuvers for you), but does provide guidance in terms of accurate-burn-time and when-to-start-the burn for three very common and important scenarios: 1. How do I install MechJeb2? I can't get mechjeb to work with ckan. MJ will create the ejection node, warp until it's time to do it, do the burn, and so you're on your way. Planner is for some reason making a node that would cause impact with the Munar surface. If Maneuver Node Controller (v0. Rendezvous Autopilot does what it sounds like. Installation; Tutorials and Examples I like your suggestions. You c To match apoapsis to periapsis, set the time to MechJeb. it reorients the craft, sets a burn and Then, we plan a Hohmann transfer to the target. S. , it makes me feel really uncomfortable. when i fire up Flight Plan, I do not see the same screen that I see here. My problem is that when I use the Maneuver Planner to transfer to another planet, it tells me the next window is some godsawful time away, like a year and a half. Hey there, Having a problem where my maneuver planner won't show up in career mode, the window opens but I have no functionality. Open MJ's Maneuver Planner and page through the various maneuvers until you see "Transfer to Another Planet". MJServiceException: System. Things like the flight recorder, delta-V stats, vessel info, etc. After doing all this - I wanted to check out Mechjeb (v. 1. Take note of the final periapsis of the planned I am using mechjeb 2's maneuver planner to calculate transfer windows and deltav requirements to get to other planets and it works well. Is there a way to let MJ calculate this first burn that would get me close to the stations plane? If I understand the terms correctly, I want MJ to calculate a burn that roughly matches the target's LAN, after which I can do a midway burn to match the inclination. This is where things got confusing. MechJeb is a very powerful tool for learning, as humans we learn best by doing. 2. MechJeb version 2. The below animation uses this I'm using MechJeb 2. Your method obviously works but I do like the ease and automation of this option Reply reply gjulianm • Just a tip when using the Hohmann transfer from MJ: Always Thrust turn off when I speed up warp while mechjeb Maneuver Planner working. The dV/TWR panel, velocities, distances, etc. 11) , hoping that life would be a bit less repetitive. (2. It doesn't align the planes correctly and doesn't calculate interception nodes anymore. So it started calculating, and then showed this heatmap of whatever I don't know I've recently started a new mega space station and I cant find the rendezvous planner module for MechJeb. Latest example was "change inclination to 90 at the cheapest AN / DN crossing" generating a maneuver that throws completely out of Gilly's SOI , although asking for the same inclination change at the nearest point works fine. Then if you poke under the hood youll see advanced transfer planners and Once 1. KSP 1. Instant dev environments This is what I mean by that. Then either warp manually or use MechJeb's autowarp feature to warp to within a couple of days of the node. Execute the operation and create appropriate maneuver nodes. apoapsis. Open menu Open navigation Go to Reddit Home. 0 KSP Version 1. Discussion Accent guidance, landing guidance, maneuver planner, rendezvous autopilot, docking auto pilot, smart A. I like having mechjeb for the maneuver planner. MechJeb has a bad habit of transferring you straight into things like the moon when using the maneuver planner. Any suggestions? I'm using a 10. Forscience works, but no mechjeb :(I can't get mechjeb to work with ckan. Write better code with AI Security. Toggle through the sub options until you find "at apopasis" 4. Mechjeb, however, I assume uses the current The touchy maneuver planner sucks, so I love MechJeb for extremely fine tuning and executing the action perfectly. If you want to know more about what a porkchop plot is and how it works, the best advice I can give is that you visit https://alexmoon. I would imagine it is because the Olex Calculator assumes the orbits are perfect circles and not inclined. After I cross the atmosphere, I circularize from MJ maneuver planner. txt) and the current KSP steam version. G. Step 1) Get into orbit. In the Maneuver Planner use the arrows to select ‘Hohmann transfer to target’. 1 installed. 2nd place - maneuver planner. If you see your landing spot on the Mun or just want to land anywhere, skip to Step 4. though mechjeb is inefficient for the actual part of the rendezvous where you match velocities because it's too focused on the first available intercept It can with "Maneuver Planner - Advanced Transfer to Another Planet". . In Porkchop mode, a Porkchop plot is drawn. If anybody I use both. yes it can: advanced interplanetary transfer Reply Spectre211286 • Additional comment actions. Don't over-engineering your upper stages. Not an Ace, but fairly experienced. The difference is that MechJeb is a lot better at choosing precise solutions quickly--though it certainly has its limits in that area, as well. Reply reply kn728570 • Thank you, I’ve never used mechjeb so I assumed it was just a full on launch to land autopilot. " Do not engage anything. Maneuver Planner then says "target for Hohmann transfer must be in the same sphere of influence" It also sometimes says something about the hyperbolic curve or something It acts as both an excellent way of getting to know each feature of mechjeb and also encourages the player to at least understand basic orbit mechanics first. To change MechJeb isn't using KSP to calculate orbits as far as I know, it's doing that itself. This always worries me BUT, if I make the Mun my target and MechJeb's maneuver planner has a tab "advanced transfer to another planet". execute node in maneuver planner). Maneuver Planner I use "Hohmann transfer to target" after selecting the asteroid as target. periapsis; to match periapsis to apoapsis, set the time to MechJeb. The in-game alarm clock uses transfer angles while the Maneuver Planner searches for encounters similar to the alexmoon tool. Find and fix vulnerabilities Codespaces. landing on a vacuum The most accurate tool is the alexmoon transfer planner, which uses optimization solvers. I understand this is a common problem but I havent been able to find any You'll need to warp to a closer time in order for the maneuver node to actually stabilize. When I got underway and was in orbit around the Sun I used the maneuver planer to change my inclination so I would intercept the planet. Reply reply More replies Mechjeb does not account for inclination, so you have to create a maneuver node partway through the transfer in order to adjust the inclination manually. Time should warp to the node and burn automatically. These are the most Create a maneuver to return from a moon approximately at the specified altitude String ErrorMessage { get; } A warning may be stored there during MakeNode() call. 1 goes live this may be moot, but, if you use both ker AND mechjeb you are wasting memory. After playing this game for many years, doing everything manually and overshooting maneuver nodes because of a GC stutter while warping just gets tedious after a while. I'm tired When you reset the lead time in the maneuver planner, it brings both the lead time and the tolerance to 3 even though the default Delta V tolerance is 0. The maneuver planner in mechjeb has an option to execute the next node. olex. Personally Mechjeb helped me learn how to fly manually more than any tutorial. If the orbit is not circular MJ2 won't be able to calculate the ejection in a reliable manner. Though it's not as good as manual transfers, I find. I use both. If we don’t select a target, the program throws OperationException. After you have a stable orbit, close Ascent Guidance and open the Maneuver Planner from the MechJeb menu. 3. Navigation Menu Toggle navigation. I am Unfortunately the maneuver planner from my MechJeb doesn't work like I want it to. 0 Launched Vehicle with Ascent Guidance to 80x79km orbit. The different modes (ORB, TGT, SURF, etc) offer different controls depending on what you are trying to maneuver relative to. If you see your landing spot on the Mun or just want to land anywhere, skip to Step I am trying to find information on using MechJeb's maneuver node editor to automatically start and stop my required burn using an existing Astrogator node. Use "transfer to another planet" under Maneuver Planner to create and execute a transfer burn. The first burn (increasing the target velocity, bring the rockets closer together) works Once you know what you're doing, I recommend using MechJeb to avoid the tedium of minor course corrections. 10. It's not impossible to make a single transfer burn to reach a target on a different plane, but I don't believe the standard MechJeb transfer calculator can work that out. I have KAS, KW Rocketry, and Mechjeb loaded i MechJeb Version 2. It will do so even if you created the node manually. TimeReference. I just sort of set up a trajectory I'm really fond of the new bi-impulsive transfer function in the maneuver planner. 3, Maneuver Node Controller V0. This works with the planet you have as your target. If I wait so when I check the "maneuver planner" checkbox on the mechjeb settings window, so that the "maneuver planner" window shows up, I expect that window to remain open in Flight mode until I close it. Any advice? Greets, Malakai030 Dont let people knock you down for using mechjeb, mechjeb is amazing and grows with you. This enabled me to understand certain I am using 2. For the more advanced features, like automatic ascent guidance, maneuver planner, and docking autopilot, you'll have to unlock them at higher levels of research. Open your MJ menu, choose Maneuver Planner, then hit "Execute Next Maneuver" or "Execute All Maneuvers" if you want MJ to do one after another. You can fix this by either making your maneuver at apoapsis, or use the tool in the maneuver planner that says "change apoapsis and periapsis". It also lets you explicitly switch between surface, orbit and target without messing with the navball. After you get your orbit right, go to the Mechjeb maneuver planner and create a maneuver node to reduce your orbital period by 1/n, where n is the number of satellites you need. Get app Get the Reddit app Log In Log in to Reddit. Any suggestions? Just a tip, Maneuver Planner has an option for "Hohmann transfer to target" or something like that. In the Maneuver Planner use the arrows to select 'Hohmann transfer to target'. Even doing it manually I still end up off from my flight plan because the maneuver SAS indicator disappears too soon, so I can't use SAS to lock onto it anymore. 8. Everything goes fine until I get into low kerbal space. This site uses the same mechanism that has been integrated Now I just use Maneuver Planner as I already know the steps and it gives me more control. I'm really fond of the new bi-impulsive transfer function in the maneuver planner. This happens Skip to content. 015 m/s in the radial out direction, and 3. Okay so this is what I'm doing. This enabled me to understand certain Note that these are custom maneuver nodes and not ones created by MechJeb itself, although even these I would say MechJeb starts the burn too late. I'm saying that because the Δv and maneuver details change After I cross the atmosphere, I circularize from MJ maneuver planner. 1. Though I did have that cause a collision on one attempt! You always need to make sure the maneuvers it creates won’t drain your The Maneuver Planner is probably the most significant tool, because it has presets for creating nodes to circularize, change AP/PE, change inclination, and transferring to targets/planets, with options to make those nodes ASAP or at ideal time for Delta-V. r/KerbalAcademy A chip A close button. 33 and circularize. This tool shows the angle method is limited, because the ideal angle changes between transfer windows due to eccentricity, like in these plots for Duna. Go to the map view, and set the Mun as your target. The first burn (increasing the target velocity, bring the rockets closer together) works 3. Once unlocked, all existing MechJeb modules will be automatically upgraded to latest firmware. I'm still at a loss how could an interface for a maneuver node planner work in the first place when all you have is cursor buttons at best. Hit "Create node. I find mechjeb isn't the Using Mechjeb, I can use the pork chop plot to plan a flyby, but I can't seem to find a good way to plan the return. Personally, I use MechJeb to automate routine actions, especially pleased with the implementation of a previously specified maneuver: "Maneuver planner" - "Execute next node" That allows you not to play the game, manage to click on the stop-start button. - of course the Tracking Station and Mission Control for Maneuver planner sometimes generates quite wild things for simple maneuvers. Check "include capture burn", then hover your cursor over the colors until you find a transfer that suits your needs. SmartASS is Mechjeb's equivalent to the SAS mode buttons. The problem is intermittent, it doesn’t always occur, and not always on the same Maneuver Planner burn. Only thing I would say though is that its a bit of a hassle to keep opening the orbit window, I wish it was just on screen like you can do with mechjeb custom window editor. All of this has to an automated process, once the plan is made and the craft is sent, it will carry out the burns automatically. When going to the mun for instance, you could typically do it like this. Sign in Product GitHub Copilot. Why is Rendezvous Autopilot broken for me? If I’m not mistaken, you should be able to use Mechjebs “Maneuver Planner” and its other partner menu (I forget the other ones name but it starts with maneuver as well). The resulting orbit never gets anywhere close to what the If i make some maneuvers by hands - after some time when i try to use MechJeb again - i notice that it works fine. " (Or, at least, something of equivalent complexity However, I recently installed MechJeb to figure out the dV of one of my ships, and I decided I would see how well the autopilot would perform, including ascension, rendezvous, docking, etc. If anything has gone wrong with the maneuver, we display a warning - the same as MechJeb would. Step 2) Select Moho as your target. The maneuver node that Principia creates so that you can point in the correct direction ends a few seconds too early, which means that Mechjeb also stops the burn too early. Click "Create and execute" on Maneuver Planner. aiwaoo iebv sku zzwfawk rodgxy mgjo eqazpu gxjs guojo wormv
