● Mechjeb orbit 5m lander docked to the front to Duna, but I'm having a small problem with MJ planning the transfer - I can get a 1k Dv transfer (though dV isn't an issue with pure quantum vacuum mode, but that lacks in thrust As per orbits, i (usually) go for a 80Km orbit using MechJeb Ascend Guidance, separate the side boosters at around 70km or so (Just before i get to the target Apoapsis so the middle booster still burns a little to avoid being too close to the boosters when i go back using FRMS). I have all the modules for it unlocked. Although its worth playing it without it at first its actually more realistic to use considering a lot of maneuvers were actually automated during the Apollo missions. Somehow when I use MechJeb trying to launch bigger modules into orbit for a space station (like MKS Kerbitat) it just can't seem to do the job. exe. [6] [7] Transfer orbits can go more than 360° around the primary. 2 . Click the research button. First, I do an EVA at the space center and put down a flag. (Though you'll see it at Moho too. This is useful for setting up things like CommNet constellations. My rockets don't get any orbits and just crash every time, because Mechjeb screws up the orbit. Set yourself to retrograde. The planner only has an option for the inclination, so I typed in 25. Everyone is different The Argument of Periapsis is essentially the angle (from some fixed origin) to the periapsis of your orbit. May 14 @ 10:36pm Mechjeb is a strange one. 5m probe core (RC-LO1) with me for the delivery ship that way I don't lose contact with the probe just in case I screw up. MechJeb PVG only just getting to orbit? I'm trying to do my first orbit and return, I've done a few orbits to complete some contracts and PVG, although great for aiming at different target apoapsis and periapsis, always seems to use all the available fuel to get into whatever orbit. Was somewhat surprised when I got Jeb into mun orbit for his first landing and saw that the McJeb landing guidance was available (and worked fine) even though I had not yet unlocked unmanned tech. If your target is orbiting at 80km, you might try a 100km or 120km orbit. Created by. Per page: 15 The fact that it doesn't play the game is exactly why one needs to know how to play the game before using it. Top. These multiple-revolution transfers are sometimes referred to as Type III and Type IV, where a Type III is a Type I plus 360°, and a Solution: Re-create the windows using the Custom Window Editor, MechJeb 2 is still in a pre-release state so there may be the occasional bug. I unlocked the Mechjeb part, but many of the options are greyed out in-flight: On this video I wanna show how a resonant orbit work. ks This file contains bidirectional Unicode text that may be interpreted or compiled differently than what appears below. Coast to the edge of the atmosphere (if applicable) 4. Mar 13, 2017 @ 9:28am thanks #2. Note your heading from MechJeb Orbit Window. 2) Get into a higher orbit and let your target catch up with you. Now here's the magic. 5 / 50 / 40 / 45 / 1) and let it rip. My ships kept exploding, crashing, and whatnot. Java Python 16 public static void main ( String [] args ) throws IOException , RPCException , StreamException { 17 //This script assumes the vessel is in orbit, planes match and the target is set. This should leave us on a nearly synchronous orbit very closely above our desired target. Instead, I let MechJeb fly my rocket into oribit and circularize it. I always just crash fall back to the ground, sometimes never even leaving the atmosphere. For more info, visit this KSP This tutorial launches any rocket into a 100km circular orbit with 6° inclination. Satellite Design. Space. select mun. how can i fix this? < > Showing 1-3 of 3 comments . Important parameter to this mode is the desired orbital ratio, which is the ratio between period of your current orbit and the new orbit. org] work, which also explains why the transfer windows to Eve and Duna are the most infrequent ones, while the transfers to Moho/Eeloo/Any OPM world are quite frequent. com/wat This tutorial is about setting advanced path parameters to AscentAutopilot. I have been screwed many times by mechjeb giving me a sub-optimum course and burning to many delta-v to complete the Advanced Launch into Orbit This tutorial is about setting advanced path parameters to AscentAutopilot. I've tried using MechJeb's Ascent Guidance set to 2868km but this ends up putting the module (If I recall correctly) 90* away from KSC. So a ratio of 2:3 can be used to set up a 3-satellite network at 120 degrees to reach other in a single launch. What else is odd about this is that the mod is supposed to help with orbital Of course, nearly all of my builds failed and I couldn't get into a fantastic orbit. So you put the carrier into an orbit with a When MechJeb gets to the "Mid course adjustment" stage, the whole thing just goes to heck and I have to end it. But because of various inaccuracies, their orbits are a bit off from each other. SmartASS class MechJeb. [MJ (mechjeb)] hohmann transfer (create and execute). Mechjeb has a landing autopilot you can engage, it's fairly efficient, and very precise most of the time. I'm just using it to test out Mechjeb, which isn't actually working right now. Mar 13, 2017 @ 9:25am Timewarp. Open comment sort options. Favorite. Please note that the Smart A. When you're already in orbit you have to do a plane-change maneuver. I'm using MechJeb 2. 0 = MechJeb. Also, it wasn't clear at that time whether the OP was talking about inverting the direction of an existing orbit, or launching from the surface into an inclination of 180 degrees, i. module provides aids for vessel pitch control. There are four main parts to the launch process, and the exact altitudesat which they occur are customizable: 1. 5 but the orbit it planned out does NOT match the 25. module is in need of more thorough documentation. Let Mechjeb plot, but you can often do little corrections with the nodes that can make them more precise. Thanks for the help! Struggling to use mechjeb in RSS, mechjeb seems completely oblivious to limited ignitions and disables single ignition engines often ending the launch, it struggles on lunar descent as well it used all 50 of my lander ignitions in the space of half a second as it couldn't start the engines due to propellant instability. Quick question about MechJeb. TimeSelector. So, with the assistance of mechjeb, I finally managed to get a rocket to munar orbit and onto the surface. 4. Posted December 11, 2014. Feb 4, 2017 @ 10:46am. 2) as you said. This is just how synodic periods [en. MechJeb then uses a guess at what your acceleration profile/direction should be to achieve Mechjeb messing up orbit So, everytime I try to get my rocket into orbit, it creates the orbit not accuratly to the planet, but completely f-ed up , like it's using the rockets position as center of the orbit, and not the planet. I don't know if I'm just having a brain fart here, or not understanding the mod, or what. If you plot the node without executing it, you can then adjust it accordingly before letting the autopilot perform the burn, but it sounds like you're already doing that. Its mass less than 2kg. Launching into the same plane does help however. The “Injection Δv” value is the delta-v required to move from the resonant orbit to the final (circular) orbit. That ship can mechjeb to any duna orbit, but not land. In the orbital map, click somewhere on your orbit to create a maneuver node. Pretty much exactly what the title of this thread says, they're just not there At all. " which is no where near For example, you have been in dunas orbit, but not landed. (From Kerbin itself, I start with something else to get into orbit, but I presume you mean from Kerbin orbit instead of from Kerbin itself. Your "orbit" is an equatorial one at that point, albeit one that has a periapsis deep inside the planet (you have an "orbit" because of the rotation of the planet, but the ground I just try to use MechJeb to get over the parts of the game i'm not interested in learning right now, landing being one of them. We start with connecting to the MechJeb is an autopilot plugin that allows you get into orbit, and go to the Mun in the fastest and most efficient way possible. 5 orbit on the map. 4 degrees, apogee I think is at geostationary orbit alt of 2868. I have tried a lot of changing the Booster pitch start value and the pitch rate but every time it just overshoots the wanted ap by a factor of 200km and I have no idea what I'm doing wrong. g I can get into an orbit of 300x300km with an amount of Δv, and getting into a lower orbit, like 200x200 Equivalent to MechJeb. Instead you go on and say I do not know how to plot an orbit without mechjeb? I know how to plot an orbit without mechjeb. . burn prograde at periapsis manually (or drop node and execute) until you are on an escape trajectory. I use 4200 - 4800 m/s for every stage (together it is 9400 m/s) and 1. 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. circularize_altitude. Thanks for any help :) Step 2: Get your craft(s) to a circular orbit with 0 degree inclination. Keep tilting the craft more and more until it is almost horizontal around 50km. I would like to thank CardBoardBoxProcessor and Keptin for their amazing MechJeb models. Share Sort by: Best. mechjeb. 18 try ( Connection conn = Connection . interface_mode: MechJeb. In this example, the satellites’ final orbits at 100,000m above Minmus will have a period of 2 hours, 39 minutes, 29. 75km, but I need to figure out the perigee. [MJ] fine tune distance as desired. I also, in a follow up post explained some ways of how to invert an orbit and what it actually takes. SmartASS . any solutions? Share Sort by: Best. Related Topics Kerbal Space Program Sandbox game Space simulator Gaming Sim game comments sorted by MechJeb Primer Vector Guidance saying FINISHED before liftoff, Im trying to launch into the plane of the Moon and the ascent guidance doesn't work. console and burn until your inclination is at 90° (you can see your exact inclination in the orbital information window). Once you're in the Mun's SOI, use MechJeb to circularize your orbit at periapsis. Anatid Robotics and Multiversal Mechatronics proudly presents the first flight assistant autopilot: MechJeb. Doing this manually/semi-manually is trivial, but I've been trying to figure out a way to transform an arbitrary orbit into a specific one using a series of MechJeb maneuvers, with reference only to the parameters specified in the contract. 14. Also, FYI, MechJeb isn't really good at doing A short little guide on how to use mechjeb with SSTOCraft File: http://s000. The dang thing won’t even get me into a proper orbit. Here is the ascent profile I am trying to use and a picture of the orbit it keeps trying t I've been messing around with mechjeb, and when I try and get an orbit with the ascent guidance and get to my targeted altitude, it just keeps pitching down and eventually crashing into the ground. the orbit just looks like a straight line. Sorry if this isn't helpful, I play a mostly stock save with only kerbal atomics and mechjeb. (Mechjeb can match inclinations Just get both craft into orbit and set your craft's Ap (if you're lower than the target) or Pe (if you're higher than the target) touching the target's orbit. Same. Open MechJeb Maneuver Planner, select 'Bi-Impulsive Transfer to Target'. I've even seen people use it to learn how to fly well and then shut it off. Using the resonant orbit function of MechJeb I have managed to place 2 Relay Satellites on opposite sides in Polar orbit around the Mun. Please help as when using the maneuver planner the same thing happens! Thanks, mbkgit I installed mechjeb, to make the mundane task of launching into lower kerbin orbit less boring and more precise. It says it is And me, well with KSP 1. It will give you a manuever node about half way to the Mun. 5 percent and watching the orbital period time in MJ like a hawk. Using stock Kerbal X i've run a series of 50 tests. T start T End Angle shape acc lim Dv fuel left in capsule what happens is, as soon as I go to launch i get that mechjeb window on the right of the screen, when I open it it gives me options like, custom window editor settings smart ass delta v stats orbit info surface info vessel info Advanced Launch into Orbit; Rendezvous with a Target; Docking with a Target; Third-party Scripts; Contributing; Report a Bug; Client Documentation. However one of my stages only has 1 ignition and it burns from launch to orbit and has 2000 delta v left. ThrustController. Mechjeb is good for teaching, and I absolutely love it, but try not to do your first ANYTHING with 5. I had my first solo Moho landing before I had my first Mun landing. Once the satellites are in the right orbit, you can fine tune by thrust-limiting your engine down to 0. AscentPVG (Primer Vector Guidance (RSS/RO)) Attribute: It is a 3-burn to orbit style of launch that can get to orbit with about 2800 dV on stock Kerbin. php/You Open MechJeb Orbit window and make sure you have Surface speed, Vertical speed and Heading at least. Is this normal and do I have to be patient or am I doing something wrong? I'm just chasing my lunar module round the mun forever it seems lol The rocket is fine, I've gotten into orbit with it before and even gotten to the Mun. Controversial. Either pick a target to land at, (one under your orbital path will require lest fuel,) or just click land now (or whatever its JNO MechJeb(Driveless Programme) It is a group of parts with vizzy that you can use it in career mode. Unfortunately, the trans section under orbital operat This is done with various orbital mechanics principles, depending on what exactly your target orbit is. (Mechjeb can do this for you) Match inclinations with your target. And it isn't doing anything. Open MechJeb A. I decided to make use of the MechJeb I’ve had for a while but never used, but I’m immediately running into problems. . View all videos. I was wondering if it is possible to use the advance transfer option of mechjeb to get to another planet while I‘m not in Kerbin Orbit. The Molniya orbit was discovered by Soviet scientists in the 1960s as a high-latitude communications alternative to geostationary orbits, which require large launch energies to achieve a high perigee and to change inclination to orbit over the equator (especially when launched from Russian latitudes). You might find it more efficient to swap steps 1 & 2 depending on the situation. I see it regularly after take-off. It seems to stop burning way too soon and then start burning again way too late. Land Somewhere: From orbit, this will perform a simple and fairly immediate deorbit and do the landing burn, usually without the weird sideways course corrections. 1) Get into a lower orbit and catch up with your target. When I try to rendezvou with my Space Station, it doesn't do anything for a while and then makes the orbit so ill land back on Kerbin instead of heading to the ship. Last edited by Tormentor89 i'd suggest You'll get answers in both directions. (I'm showing the more interesting ones only to save space). 3 Localization fix; MJ does what a friend of mine describes as "stutter warping" - after the Once arrived at the planet, capture into an elliptical orbit with the apoapsis at the edge of SOI, and use MechJeb to plan an inclination change to exactly 90 - it should make the node on the side of your orbit farthest from the planet, so this inclination change should also cost very little. In terms Open the target orbit info window in MechJeb, click the small "E"(dit) in the top left corner and add to this window "Target Time to AN" and "Target Time to DN" - this will show the time remaining until the Moon crosses the equatorial plane Select the Moon in Principia (Select target celestial from the main Principia window) MechJeb Orbit Issues . My staging is First engine Release launch clamps and fire SRBs Drop SRBs Fire second stage An orbit which traverses less than 180° around the primary is called a "Type I" Hohmann transfer, while an orbit which traverses more than 180° is called a "Type II" Hohmann transfer. phase. Am I on the right track? I want this spy. It was like a huge light blub going on. For example: My craft is in minmus orbit and I want to transfer to Duna. Tormentor89. newInstance ( "Rendezvous with a target" )) { 19 krpc_mechjeb_smartassinterfacemode_orbital krpc_mechjeb_smartassinterfacemode_surface krpc_mechjeb_smartassinterfacemode_target krpc_mechjeb_smartassinterfacemode_advanced krpc_mechjeb_smartassinterfacemode_automatic internal mode, do not set. Best. The MechJeb autopilot, when used with ascent guidance, seems to take me into random encounters with the Mun etc if I call for the altitude of orbit asked for (18,692,804 meters, or about 18,692 k(?)). Leaving Kerbin's orbit first and then trying to do a transfer burn is incredibly I can't seem to get the advanced interplanetary transfer (or whatever it's called) to function. Award. type krpc_mechjeb_smartassautopilotmode_t krpc_mechjeb_smartassautopilotmode_off Transfering to another planet starting in minmus orbit via mechjeb . You can use mechjeb to circularize at a particular height, so long as that height is between your current apoapsis and periapsis. However I only used the info panels (you all are right about rocket view peri- and apoapsis being super useful). The Ascending Node is the angle to the point where the orbit crosses the equator. 1 second burns etc. Because otherwise, just get a circular orbit at 35,786km above the equator and RCS to fine-tune your orbital period as described above -- you will need Kerbal Engineer, MechJeb, or other mod that shows you your orbital period. So, I did my first orbit (in simulation) yesterday, using MechJeb PVG because I wanted to see how that worked. Kerbal Space Program. If you're using MechJeb "fine tune closest approach" is your ticket. When it reaches 0 it means that my rocket on landing pad is inside moon's orbital plane. Resonant orbit is useful for placing satellites to a constellation. The Deorbit burn seemed to be successful, but the Braking burn was sputtering and jittery, and the final landing site was 130 I’ve landed on duna and am trying to use mechjeb to launch into a similar orbit as my mothership but mechjeb keeps launch into a retrograde orbit compared to the mothership. MechJeb hyperbolic orbit so i am using the mechjeb advanced planet transfer and it says " initial orbit can not be hyperbolic " . Then I turn flags on in the tracking center view, so I can easily locate the KSC. As a result, OKB-1 sought a less energy-demanding orbit. Parameters. Mechjeb launches are EXTREMELY useful for space shuttles because the precision of the computer takes account of What I can't seem to figure out is how to get the Mechjeb to establish a orbit around Mun not just fall into it after the transfer. Resonant Orbit Calculator For Kerbal Space Program . Initial ascent 2. 3 2. Sarxis. It needs to be able to execute the burns fairly quickly to get it How to use the MechJeb autopilot mod to orbit The Mun. Doubly so for atmospheric landings. Once circularized, set the space station as the target. Unfavorite. Circularization burn at apoapsis See more How to use the MechJeb autopilot mod to get into orbit. I have no idea how I'm supposed to get heavy I'm currently orbiting Minmus with a satellite, which needs to be put into a specific orbit (contract). Eve's inclination relative to Kerbin doesn't matter much, since Mechjeb will ajust your orbit the minimum amount needed to get an encounter at the intended altitude. GUI mode; doesn’t do anything except changing SmartASS GUI buttons to a specified mode. Each launch was up to 100x100 orbit, every test was ran without terminal velocity limit as Kerbal X is nicely designed around that already. Gravity turn 3. com seems do be gone. Moreover, a rocket launched is never manually piloted. The capabilities available with mechjeb made it much less arduous to carry out increasingly complex mission profiles and systems. com/index. In fact, it seems I can control the pod/craft far more easily by hand than I can with MechJeb, which makes the mod not as useful as I thought it would be. MechJeb has a Match Planes function to give them the same inclination, but is there a function I can use use to match the rest of the orbit too? How do I MechJeb 2 to circularize an orbit? Mods: General [M] Probably my biggest use of the mod, or at least it was, years and years ago, back when it was mechjeb 1. Don't expect MechJeb to figure out a long, slow burn using ion engines or other extremely low thrust-to-mass ratio vehicles. then plan a circulization burn at the mun. C-nano; C#; C++; Java; Lua; Python; External Resources. wikipedia. Then zoom forward in time until you change to the Mun's sphere of influence. 9 for 2 stage, Hello, When I select moon as a target then in Mechjeb's "Rndezvous Planner" i can see relative inclination. The complete program is available in a variety Mechjeb's Landing Guidance goes a long way here. target the docking port of the new ship that you Unfortunately I can't help you with the MechJeb questions, but LAN means Longitude of the Ascending Node. I don't think I ever saw it before installing MechJeb. BTW, I always use bi-impulsive xfer for low Kerbin orbit to the Mun. To deploy satellites, set the denominator to I'm trying to use MechJeb with Galileo planet pack. #1. This was workable but not optimal since it would occasionally go out of contact with KSC. MechJeb, on the other hand, is trying to make a proper gravity turn, and your Mechjeb isn't a crutch; quite the opposite, playing without it is giving yourself an unnecessary handicap. Docking autopilot is another thing, it's horribly inaccurate from my experience. The lowest delta v transfers will alter your orbit just enough to get you to your target, which will create a nice curve that barely touches the target's orbit. A bit of blue orbit comes off of Kerbin, then there's a gap, then the top part of the orbit curving back down, then another gap exactly symmetrical to the first, then the last bit of orbit down to the surface. Typically I have to do a manual landing or two before I have enough science to unlock MechJeb is an autopilot that helps fly your spacecraft, it'll do the boring stuff, or the exciting stuff, depending on your preference, but, you can point an First, place your orbit into an escape trajectory from Kerbin. Mechjeb Hyperbolic orbit? Mechjeb Hyperbolic orbit? By Space. Thanks! Greetings, one and all! During a recent mission while going through the Kerpollo Challenge, I realized that there just wasn’t a full-length tutorial on how to use MechJeb 2 for docking. com for more in The "remove all nodes" being available and warning "initial orbit must not be hyperbolic" means it already calculated and executed one node, and it expects you to be intersecting the node on the opposite side of the planet yeah? If thats so maybe it got confused on the timing being several months away (like another user said). Make sure your rocket as enough isp ( more than 1. The best way to get into orbit then is by doing a gravity turn. Calculate the resonant orbit needed for a carrier craft to inject craft it carries, like satellites, into equidistant positions of a shared circular orbit. Switch over to the ship you just met in orbit, select 'control from here' on the docking port that you plan to connect with. How do I get it to launch the opposite direction? Archived post. 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. Then either warp manually or use MechJeb's autowarp feature to warp to within a couple of days of the node. It is a 3-burn to orbit style of launch that can get to orbit with about 2800 dV on stock Kerbin. Use MechJeb to launch your ship into a nice little circular Kerbin orbit. New. I'm trying to send a 3. Another possibility if you built the ship from several Kerbal Space Program satellite orbit phasing using kOS and MechJeb Raw. That is, one burn from a parking orbit to GEO, or close to GEO, with minimal adjustments if the user wishes. tinyupload. The reason the maneuver is 80 days away is because you have to wait for the planets to be in the proper position so that when you reach your solar apoapsis, Duna is right there to capture you. It did a Low Orbit Plane Change burn to bring the orbit in line with the target, which was perfect. 65-0. I line up my view so that the camera is in the plane of the target orbit, i. once in an orbit round the sun, [MJ] hohmann transfer to the planet of choice. For more info, visit this KSP Ascent, kerbin orbit, transfer to another planet. Open comment sort options Another thing The best I've been able to do on my own was an orbit with an AP~2900km/PE~2600km/INC 0*. Step 1: Understand What a Geostationary Orbit Is Started a new career today (while watching the Starship livestream IRL). Q&A. This will drop your periapsis just enough to cause you to advance 120° relative to the first satellite when you get back to apoapsis. Or instead of going 90° right off the bat go something like 75° or 80°. Then at that point, redo the porkchop plot to get a new maneuver node, and then you can use MechJeb's node executor. com/KSP Site:https://kerbalspaceprogram. Reply to this topic; Start new topic; Recommended Posts. This mode should be used starting from a orbit in the desired orbital plane. I think you're incorrect about synchronous orbit though. Archived post. youtube. Do I have to unlock Mechjeb in Sandbox mode? No. Mechjeb seems to get me to within around 1. (Click the double-arrows to do it). Active part ''JNO MechJeb Switch'' to choose the function. I use MechJeb all the time these days but that's after I learned how to achieve orbit, how to rendezvous and dock, what delta v is, what a Hohmann transfer is, and developed an understanding of how orbital maneuvering works. I can share a link to a video demonstrating this. Once you are in Kerbol's SoI, go to your 'Orbital Operations' and go to transfer - Duna, place your Periapsis ~8 KM. The complete program is available in a variety of languages: Java, Python. If a warning pops up, you can ignore it unless it is something like "Your inclination is 180 and the target is Circularize your orbit. But if you'd like to pull together a sizable fraction of those capabilities and you're willing to split this across a few different mods, then *you're in luck!* **Flight Plan** brings you many of the features and capabilities you might remember from Mechjeb will also say that you are already orbiting eve if you have a maneuver already planned out to get yourself there. Toastie Buns. Folks seem to like matching orbits first, but it literally does not work like that to the extent that doing so will prevent you from rendezvousing. Another thing to keep an eye on is Ap altitude and time to Ap (in MechJeb's orbit window) - pushing the latter out so that there's enough time for your circularisation burn is a good thing to monitor. " #13 < > Showing 1-13 of 13 comments . Set it to like 200km. Now, I can do with or with out, but I like playing to build stuff, not so much fly. php?file_id=07417282472420864207 At the selected MechJeb. I want to use that dv, but mechjeb shuts the engine off and the engine can't ignite. Doesn't really bother me, it's just strange. AscentGT (Stock-style GravityTurn) 2 = MechJeb. And for those wanting to tell First of all, we start with connecting to the server and initializing MechJeb service instance. New comments cannot be posted and votes cannot be cast. You have not enough delta V (for fly with your TWR) or you have bad TWRs on stages. I clicked on the research group but I still don't have the Mechjeb tech: Click on the Tech Group icon, then go click on the individual mechjeb tech that appears in the right-hand window. 75m anti-matter craft with a plasma thruster (on quantum vacuum+liquid fuel) and a 2. All in all, it was very satisfying getting a circular orbit using the map tool only and with only minimal assistance from MechJeb. The problem is that it keeps launching so that my 500km apoapsis is above the north pole, instead of the south pole where it needs to be for the final orbit. Current version: 2. Doing this, along with checking the variometer to make sure your vertical velocity remains positive, is a more appropriate way to adjust your trajectory than keeping 45º pitch up, The single biggest problem with MechJeb Landing Guidance is horizontal velocity and anything resembling a long horizontal flight time or shallow trajectory. As a retired engineer, I'm trained to state things more precisely because sometimes a sloppy statement I show you how mechjeb makes ksp a lot easier to get into a perfect orbit with a small probe. fenn. If you can give me a link to a video or a webpage or even just give me some step by step instructions that'd be great. If you want to have fun make a rocket that is basically a nose cone, a jumbo-64 a mainsail and some fairly Mechjeb's Rendezvous Autopilot isn't the best thing in the world. I haven't played in a while so im sure its something really simple thanks for the help. In order of decreasing precision, the best choices are Vessel Orbital Information Display, Kerbal Engineer Redux, and MechJeb. (assuming you've mechjeb. Basically, the point at which an inclined orbit crosses the equator. Unfortunately, it seems to get confused and isn't able to properly put me in a circular orbit. e. AscentClassic (Classic Ascent Profile) 1 = MechJeb. My new engine With Kerbin, a low orbit requires a craft to be traveling almost 2300m/s. ) Launch to orbit. A resonant orbit is where the orbital periods can be reduced to an integer ratio, so their orbital periods don't have to match (but 1:1 is still an integer ratio). Favorited. Any ideas?I think the orbital inclination is 63. For me, MechJeb made KSP boring, so I have no trouble not using it. com , and I'm very unsuccessful in my web search Orbit Inc, degrees - Target inclination, note that inclination less than your launch site latitude rapidly becomes very expensive (broadly equivalent to a plane-change maneuver of the difference in degrees in low-Earth orbit). The main application of this type of orbit is setup a communication network with multiple satellites. I'm having a bit of trouble using mechjeb to rendezvous in orbit. Space Port Site:http://kerbalspaceport. 1 and the dev version of the mod. Input and function: 1:Launch 2:make orbit circular 3:change the height of Ap and Pe 4:land on somewhere 5:land on target So I have gotten a lot of orbits with mechjeb but it's struggling to get me the first sun synchronis orbit contract, not by eccentricity but just getting to that orbit. Corvus Online Posted . Hello there, so i wandering if anyone know how to set up the aircraft autopilot of MechJeb? I try to settle the altitude hold but he won't stop to do roller coaster. Does anyone have a fix? Mechjeb is not a magician, if your rocket is bad engineered, it won't work. com/watch?v=ijaaNvVYrpUThis tutorial explains how to use MechJeb to do almost all the work for you for orbital Finally: The goal of this tutorial is not just to describe how to get a payload into geostationary orbit, but how to get it at more-or-less a precise longitude with a minimum of fuss. I highly suspect that it isn't a problem with MechJeb, because I used the MechJeb pod on top of someone's anti-matter engine add-on to land on Minmus and come back, and did it with no problems whatsoever, Either use mechjeb's ability to circularise your orbit when your ship gets to the periapsis, or plot and execute a node manually. Yes, there is a mod called MechJeb that can automate the process. The Smart A. So far as I know there's no function to set up a complete orbit. Every time I select a point on the porkchop menu / heat map, select a target planet (Jool), and click "Create and execute", it always gives me a message saying "Initial orbit must be hyperbolic" and won't complete the maneuver. Next, landing. Step 1: Burn prograde from Low Kerbin Orbit until you escape into a solar orbit Step 2: Bring up Mechjeb Manuever Planner and select the 'Hohmann Transfer to Target Option' Step 3: Select a target (I picked Jool, because I wanted to visit Laythe) Step 4: Hit plot and execute. Circularize and drop another satellite, again drop to 2/3 period, go around one more time (now advanced by 240°), circularize, drop the third . AutoModerator Best way to rendezvous using MechJeb2 is to use the Ascent Guidance to Launch to Rendezvous, then click the Autopilot button once you've attained a stable orbit. 7. So I don't feel cheating using computered ascent guidance. MechJeb. This thread is archived New comments cannot be posted and votes cannot be cast comments It is easier with Mechjeb but I prefer to use my scarce time playing doing goofy thing things in orbit, landing etc than dealing with the launch. So, if two orbits have their periapsis on the opposite sides of the planet, then their arguments of periapsis would be 180 degrees apart. S autopilot calculates it's pitch, bank and roll according to the orbital flight path and will not follow the flight path marker on the artifical horizon but will instead calculate Try launching into an east orbit then plane change into a polar orbit. I need help figuring out altitudes for a Molniya Orbit in KSP with a period of 1/2 a sidereal day. 12. First off I’m running a pretty old version of KSP, 1. Wait until you get near the place you want to land on - ideally Starting from a 25km circular orbit, I opened up MechJeb, picked 'Enter Target Coordinates,' and input 0 Deg 42' 6" N, 22 Deg 44' 45" E. 0. If you want to have fun make a rocket that is basically a nose cone, a jumbo-64 a mainsail and some fairly big fins, have the pitch program flip it over aggressively (uncheck the AoA limiter, set the values to like 0. To review, open the file in an editor that reveals hidden Unicode characters. 5 ) fins on the lower stage However I don't know how to do that using Mechjeb and any tutorials are from before mechjeb 2 and so use words and feature that have since been removed. The screenshots all use Kerbal Engineer, since that’s the mod I’m most familiar with. As someone said before, having MechJeb let's you focus on creativity and fun builds instead of functional By 'near-Kerbin I mean pretty much anything inside Mun's orbit. Then I tried turning off autopilot before it turned the engine off, but it auto turned it off too. The problem is, I generally have a stage separation during my circularization burn. I just discovered MechJeb and am trying to learn how to auto-orbit around Kerbin. 67 TWR for 1 stage and 0. Once I got back up to a 5km circular orbit, I found that there was no way to get home save my (incredibly inept) manual piloting skills. The MechJeb Aircraft Autopilot . Then one day I decided to do a new save without MechJeb. Had I been using the MechJeb autopilot, the mission would have The easiest thing is to put the carrier craft into an eccentric orbit with its periapsis at the altitude the satellites should share, and an orbital period 4/3rds the length the satellites will have in their circular orbit. Kerbal Space Program is a space flight simulation video game developed by Mexican studio Squad for Linux, macOS, Windows, PlayStation 4, PlayStation 5, Xbox Probably no one thinks of it this way, but I used to use Mechjeb as a sort of tutorial in the earlier game. I prefer bringing 6 Kerbals and the 2. If you could suggest some input I could put into MechJeb for getting to orbit, that would be great! I was following a tutorial from Carnasa on YT to build my first RO orbital rocket, but in the tutorial he doesn't use MechJeb to get to orbit, and I'd like to do that. You need to be in a different orbit with a different orbital period (slightly different is fine though), then find a maneuver that has you crossing the target orbit at the same time that the mechjeb features need to be unlocked through the skill tree, ascent guidance is pretty early on the list. Suggested mods to find include: MechJeb Thanks for watching guys!!, any questions or comments?Here are some of my other videos on Mechjeb:Landing on the Mun with Mechjeb: http://www. Related Topics Kerbal Space Program Sandbox game Space simulator Gaming Mechjeb (at least in my experience) always plots a direct intercept. [3] Studies found 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. S. I built out a combination mining rover, gas station, and interplanetary transport to make all of the other missions playable with a smaller launch vehicle because all the fuel and space propulsion were in keo already. Once you have rendezvoused with your target ship in orbit and are within docking range (either done by hand or done with Mechjeb) simply select your target docking port. He uses KER to figure out the apoapsis heights and orbital periods but you can for sure use Mechjeb's own orbit stats/vessel stats window to determine your own orbit periods. I run time acceleration until the KSC is just crossing the plane of the target orbit. I have a craft with 9800m/s of Δv in the first 3 stages and a 3rd stage with 3500m/s for a lunar impactor. S and select Surface control - Heading (the one you noted above), Pitch 0, Roll 0 (make sure it's selected). Members; 10 94 About me: Rocketry Enthusiast Share; Posted December 11, During the ascent stage, Mechjeb creates a node and upon arrival, says its circularizing but doesn't increase the throttle. I'm generally able to match orbital periods within 1 or 2 hundredths of a - Wait a full orbit of the satellite, and Kerbin should rotate to put our target_longitude right underneath. Thanks for your assumption that since I can't do it with mechjeb mean I cant do it without it Your part is actually on you because you only said "Plan a transfer to the mun. Generally speaking, you can do one of two things to rendezvous. I use ascent guidance for it. T Please help expanding this page. E. Sort by: Best. If you are in solar orbit, you can just use the Hohmann transfer tool. ) If your target planet's orbit is inclined with relation to your departure planet's MechJeb Ascent Guidance Failure "Target Is Unreachable" Share Add a Comment. 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 whereas you can usually get a more Part 1: How to get to OrbitFull video of how to get to the Mun and back, fully automated using MechJeb 2 and the ALCOR pod will be coming soon! For now here' This is a sequel to this: https://www. kRPC Documentation; MechJeb2 Wiki; kRPC. I have my unmanned probe and enable the Auto Ascent and set the orbit to 100 km (I've also tried 90 and 80). Now I will do somethings because I can do them better or I enjoy it, and I let mechjeb do all the boring work. the whole thing, every tool i need to use along the way. 5 seconds. if you want all of mechjebs features unlocked at the start you need to install a secondary mod alongside mechjeb. For exemple: when i set it for holding 1000m he The transfer from Kerbin orbit to Munar orbit is actually pretty simple to do with MechJeb handling all the tricky bits before and after. Match inclinations, if needed, at the Ascending or Descending Node (AN/DN) nearest your Ap. 4-1. If you haven’t already done so, please read The First Launch tutorial. With Mechjeb : 1) as you said. I've searched youtube but haven't found anything dealing with this specific MechJeb tool. 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, Right now I'm trying to get a simple satellite to orbit around Earth. Please help! Launch normally, use mechjeb to circularise your orbit at the desired use mechjeb (orbit operations) to set your apopasis above your target, say about 40% higher or so use mechjeb (orbit operations) to circularize at that height set the target in map view use mechjebs rendezvous module to align orbits make I know how to do this change with regular nodes, but I was wondering how this can be quickly done with the mechjeb “change inclination” maneuver planner. I believe you can also set the contract orbit as a target and have mechjeb match planes with it. Last night's docking mission was the most intense, hair-raising, exhilarating gameplay experience I've ever had in any computer game. exe December 11, 2014 in KSP1 Technical Support (PC, modded installs) Share More sharing options Followers 0. Open comment sort options It means that PVG cannot fing Trajectory to get orbit. First of all, you need to set the ascent path you want to use. Show hidden characters // Change the phase of Circularize your orbit, drop one satellite off, and then use MechJeb to get a resonant orbit with 2/3 the period. You want an orbit that is a bit higher or lower than your target. Sarbian is the current maintainer. Mar 13, MechJeb PVG changing stages . In this tutorial, I show how to achieve orbit using MechJeb. It will pretty much drop The final orbit needs to have a periapsis above 500km, so what I want to do is launch into a 200x500km orbit, and then perform a maneuver at apoapsis to get my final orbit. You're on an escape trajectory if you're hyperbolic, good sir or madam. The drag from the atmosphere of Duna should put you into an orbit of Duna. Using Mechjeb you have to wait until your satellite is above Kerbins equator and then push either "NML +" or "NML -" in the Smart A. Has anybody else had this issue or have an Also more updates on Mechjeb to orbit stock front. #2. I had never attempted docking before doing this challenge, and so I scoured the forums and Reddit and Facebook and every other nook and cranny on the internet, hoping to find Most people use mechjeb to complete orbit circularization #401,233,905 for them so they can do the more interesting, fun things. Hello, Mechjeb makes my orbit all messed up when I launch, so one side of the orbit makes my ship start burning. Anyone has a copy of manual? All links are pointing to wiki. e retrograde. To learn how to use it, visit the wiki. It's one of the key parameters that define an elliptical orbit. Here's a quick outline. Flying a SSTO with Mechjeb - Launch, Orbit, Reentry, Landing. That took months. It never makes the proper adjustment. And Please check out https://kerbalspaceprogram. SmartASSInterfaceMode . Think this would make it more fun then just giving commamd and forget 🙂 Reply reply Beeblebrox-77 • • Edited If you're looking for a *single* KSP2 mod that can do everything that MechJeb did (and still does!) in KSP1, well you'll need to keep looking. The point of this thread is "Why is my mechjeb messing up orbit circularization #401,233,905 when I'm used it to it being so flawless" not "let's convert everyone to not using mechjeb. I've tested the upper stage (simulation from orbit) and it does what it needs to, but PVG insists on using this upper stage to circularise orbit. MechJeb2 is a mod for the game Kerbal Space Program. Specifically, I want it for when I need my initial orbit to match the plane of another object, or to meet a satellite contract. It turned out I had watched MechJeb do everything to many times that I picked it up super quick. 7km and then just faffs around a lot - doing loads of 0. If you're using MechJeb, this should be a routine orbit adjustment. - Command MechJeb to circularize at the starting_apside, and execute. MechJeb uses the current state of your craft on the launch pad, as well as the target parameters it just calculated as boundary conditions to an Optimal Control Theory problem. 135: Unique I'm not embarrassed to say that if it wasn't for MechJeb, I would have had to resort to YouTube to learn how to get into orbit. (With Gravity Turn it's just click 'launch' really) Note to be careful that you do *not* launch to the same altitude of the station. Old. Hey, r/KerbalSpaceProgram, I'm having a bit of trouble with MJ2. [MJ] circularize at periapsis Edit: So I used MechJeb to get a space station in orbit. Tutorials and Examples; View page source; Tutorials and Examples This collection of tutorials and example Howdy,I have learned how to orbit Kerbin and have even made it to Minmus and the Mun and back. Learn more about bidirectional Unicode characters. I engage au So I'm using mechjeb to automate my orbits, and I'm trying to go to venus. I have the "First Artificial Satellite" contract and the "First Scientific Satellite" contract, but I also took a contract for a polar satellite (which is also fulfilled) and for a solar-powered satellite. Share. In fact, get yourself into orbit around an airless body, open it up and hit Land Somewhere, and you've got a pretty good chance of nailing your first Mun landing completely hands free. So i got my ship in an orbit around the Mun with a periapsis a bit above 26km and an apoapsis of 138, and activated autoland. hgcyxckvdkdvkexqjanxgqnxdncpqrkbepjdxtslxyzhbuaqaooyn
