I'm going back to the drawing board on my relay satellite network. Earlier I placed 3 satellites in a 1000 km orbit over Kerbin. I made sure they were 120 degrees apart (not exactly, but +-1 or less), made their AP and PE very close (and of course, they were in circular, equatorial orbits). Then I made small burns so that they all appeared to have the exact same orbital period, down to the second, as reported by MechJeb (I didn't put engineer on these ships, though I will during the relaunch if that is recommended). All was well, and during standard warping everything worked fine, but during a transfer to Jool, everything, once again, got all wonky and one of my satellites noticeably drifted, because, I'm guessing, MechJeb is limited to reporting orbital period by the second and maybe it's not accurate for this purpose? I couldn't figure a way to get the semi-major axis to display, so I haven't matched those. Can anyone assist?
