Velo24

Updated with some pretty cool algorithms as demo. Will be posting a video demo of them soon.

Ah I see, so broken:( = 0 thanks

just out of curiosity, does anyone else get a karborudum abundance of "broken:(" when they try scanning at ksp?

Hi guys, I'm trying to make an add-on which will include closed-loop attitude control with tracking (I can tell the ship where to point and it will point in that direction). The problem I'm running into is that the frames of reference for the different attitude variables are all over the place. I'm currently struggling with keeping the ship aligned with the pro-grade velocity. For an orbit around Kerbin, I'm using vessel.orbit.vel to get the velocity vector. I've confirmed that this vector is given in the Kerbin-centred inertial (KCI) frame with the z-axis parallel to Kerbin's axis of rotation. For my attitude I've tried vessel.ReferenceTransform.localRotation and vessel.ReferenceTransform.rotation however I do not think either of these have coordinates which are aligned with the KCI frame. I also tried extracting the rotation from vessel.GetFwdVector() but, again, this information is provided in a frame of reference which is not aligned with the KCI frame. Does anyone know of any rotation information available to me which is in the KCI frame, or, any velocity information which is available in a frame also containing rotation information?

I've actually got the same problem on my server. I tried playing with the settings on the server side and removing the NASA mission but no combination offers relief. The tracking station does work if no ships were attempted to be deleted, i.e.: if I launch a ship, I can come back to it as long as no one tried to delete that ship or any other ship. Once one person tries deleting their ship, its broken for everyone.

write to file? this allows Matlab to take direct control, simulink can fly your ship!

I'm guessing I'de need a mod to change that... I'll see what I can do, thanks.

KSP MATLAB All credit goes to Insulinshock! Here is a simple plugin which allows MATLAB to communicate with KSP. This plugin allows MATLAB to read basic spacecraft state-space information as well provide fly-by-wire inputs to the spacecraft. This addon is primarily for other developers to prototype controls/navigation algorithms. Update - Two demo examples added. These were developed for a course so they do ask the user some questions. - More functionality added to interface code. - Quaternion feedback control algorithm finished and added to demo code. - Documented all command IDs Current limitations/Issues - MATLAB cannot control spacecraft in parallel with SAS or user inputs. How to use: 1. Queue MATLAB to connect to KSP 2. Load vessel in KSP with MATLAB attached Autopilot KSP must be in Autopilot mode for MATLAB to control the vessel. While autopilot is on, the user cannot control the vessel. Open Source It is unlikely I will be doing very frequent development so I invite the community to contribute MATLAB code of their own.
