Check on all three. I only map at 50x, and that hasnt been a problem. As for the brain on board, i run mechjeb and remotetech, and both are taken care of, remotetech for the base capsule with the 5000 km antenna, and a mechjeb addon brain for the nav computer. I have two satellites taking care of the connection with remotetech, and I am able to control the actual satellite the entire time. It just seems like when I get into "orbit" (ie, over about 80-100 km) and I stage, I seem to lose the ability to map, and it doesnt come back, regardless of what I do (restart flight, restart kerbal, restart computer). If i build a rocket that can actually lift itself into orbit without a stage, i can map, but I have a gigantic satellite, and would like to use the satellite i built instead. Thanks, by the way, for the reply.
