KSP Trajectory Optimization Tool v1.6.7 As of v1.5.9, KSPTOT requires the use of the MATLAB Compiler Runtime R2017b! If you are upgrading from a version older than v1.5.9, please download the new MCR below! Description The KSP Trajectory Optimization Tool (KSP TOT) is a piece of MATLAB-based software I've written to help plan and execute space missions. It's functions are many: Using a Lambert solver, generate "porkchop plots" that assist with determining proper departure and arrival times of interplanetary transfer orbits. Using the d

Hi there, I'd like to suggest a small and easy contest, which is all about launch efficiency, trajectories, gravity turn, etc. You'll find below a Full Stock Craft : https://cdn.discordapp.com/attachments/706948521735225374/753224100033462372/KSC_-_SLG4_-_MunAr.craft A quick VAB pic of this very basic rocket : What you can do : - tweak every contextual parts menu : engine's gimbal, booster's power, fuel capacity, fairing jettison option, Autostruts, Rigid connection, fuel consumption priority... Etc. - modify the staging : fairing separation so

Ages ago i saw a mod, allowing to see trajectory's prediction in flight scene. But it has been lost. Now - it back. Just displays trajectory predictions. Partless, ON/OFF and nothing more. (adds itself with the help of MM-patch to each unit with ModuleCommand). This mod is designed to help with a more accurate landing. If activated in the flight scene, it will draw the trajectory and predict the point of contact. short review full review from Kottabos Download from Spacedock DONATE Source installation: remove previous versio

Hello fellow Kerbals... I just wanted to ask if there's a mod for better interplanetary encounters ( 1.7 ) because mine are often pretty terrible...

Hey all, I'm trying to do a crewed lunar flyby in RSS, and I don't really have the tech yet to build a crewed lunar orbiter yet. I was planning to use the science I got from the flyby to unlock better engines and allow a follow up orbital mission. I was planning to do a nice free return trajectory, but I seem to be having serious problems plotting what I am after. Ideally, I want a free return trajectory with the lowest possible perilune (for the science), that is less than 15 days from launch to reentry (life support), and especially a posigrade reentry. I've learned the hard

Modern ICBM are using solid rocket engine which cannot change deltaV. I wonder how it calculate the launch profile to control the target location.

Yeah, so I would have liked to post this in the Addons section because I'm looking for help from coders and/or math geeks, but since it isn't really KSP-related, I decided on this place. Mods, please do move the topic if you feel it would fit in a more specialized section. Anyway. Here goes: I'm making a little 2D arcade space game that basically puts "Lunar Lander"-like elements in a tiny solar system with orbiting planets and moons. Fuel efficiency is obviously going to be an important gameplay point, and so I want players to use gravity assists etc. For that, I need

I tried to install a tajectory mod but i don't get it working and I tried to do it in diffrent ways help.

Nothing to see here. Move along. Maybe go install "Trajectories" and, in map view, zoom out.

Hi, What I'm trying to find out if it's possible to do a brachistochrone curve/"straight" line trajectory. Essentially, you would burn towards, say, Duna until you were halfway there, and then flip around and burn to decelerate. I've already made an engine that can burn for that long, I would mainly like to know how I could do this in-game and how I could determine the halfway point of the path (roughly speaking). Thanks!

Seeing as Principia is getting to the point where it is quite useable, it seems to be a good time to do this. The challenge is fairly straight forward. A space station has been placed in a magical square orbit around Mun. The objective is to pilot the cargo vessel, which is in low Kerbin orbit, and rendezvous with the station, using as little delta V as possible. You will need a 1.2.2 installation of KSP with a stock planetary setup, and Principia Catalan, then load this save file. https://www.dropbox.com/s/d9vbdw0wba0jkxv/rendezvous.zip Rules: No use of ch

My map view breaks as soon as I achieve escape velocity from Kerbin; the orbit line will disappear, I can no longer place maneouvre nodes, and the frame rate deteriorates. I've tried reversing the orbit line fade direction and reducing it to 50%, but it makes no difference. Is this a known bug?

I took some data from ksp using KOS and came up with a trajectory plot in MATLAB. here is the result: I'm flattening my trajectory at 150km for the moment because the script parameters for trajectory. this is my first plot to work these parameters, next weekend goal: optimize it!

When you're flying a tall, wobbly rocket, the trajectory lines jitter about and it's very hard to plan precise course corrections for distant intercepts and flybys. I initially thought the jittering was just due to rounding errors causing uncertainty, but today I found out it's caused by wobbling of the spacecraft, which really ought to have no effect on its trajectory since the wobble does not affect the center of gravity. Apparently, the projected trajectory lines (orbits) are based on the current speed of the cockpit (or root part) while they ought to be based on the speed of the
