[WIN/MAC/LINUX] KSP Trajectory Optimization Tool v1.6.9 [New MATLAB Version!] in Tools and Applications Posted August 27, 2022 On 8/22/2022 at 7:04 PM, Arrowstar said: I assume you're talking about that video I put up a year or two ago on Vimeo. It actually was pretty easy. In Launch Vehicle Designer, I created a custom reference frame with the spacecraft at the center, the X axis pointing from the spacecraft to KSC, and the Y axis pointing from the spacecraft to the Sun. I then used that reference frame to steer the vehicle, just setting the steering angles to 0 deg right ascent and 0 deg declination. To get that into KSP, I used the LVD function which creates a special CSV file that is read in by a kOS script that comes with KSPTOT. That does the steering in KSP. Let me know if you have any other questions! A quick question is there any guide on how mission architect works?
