I don't know if this is the correct forum to ask for help, but tried at r/kos on reddit and they could not help, so I though I would try here. I have made a script that should take a satellite to orbit. I am using remoteTech and the problem is that my satellite becomes uncontrollable when I loose connection to kerbin. This should only happen if I try to control from kerbin, but this also happens when I copy a script to my satellite and run it. The whole idea behind using KOS (for me that is) is that I can have some predefined action that my satellite should take - and independently of its connection to kerbin - it should do it. A link to the complete file, as .txt, is here as readable through a browser: https://www.dropbox.com/s/2xqjow7habxidvi/A2.txt?dl=0 . Only the last part is interesting, as the initial part with ascend goes well i.e. it is circularizing the orbit that is problematic so I have just copied last last part of the code here: WAIT UNTIL SHIP:ALTITUDE > ORBITHEIGHT. // pause here until ship is high up. print "test 2". wait 10. SET WARP TO 0. print "test 3". wait 10. LOCK STEERING TO HEADING(90,0). print "test 4". wait 10. SET throttleValue to 1. // full throttle print "test 5". wait 10. A video of the whole ascend and circularizing is at https://youtu.be/Kru6-9Z88H0?t=366 set at 6:15 for the problem. I have activated RT in kos menu and I don't run the script from 0, but I copy it over to the satellite and run it from 1. Can anybody tell me what I am doing wrong ? Thanks in advance for any help you can give.
