Local Maneuvering

Server sat displacement distance versus time is approximately $ 0.1 a ^2 $, where $ a $ is the peak acceleration from light pressure. If the peak acceleration is 20 microns per second squared, then a server sat can maneuver these distances in the given period of time:

If the wavelength is 8mm and the ground antenna is 500mm across, the aperture is about 0.5 degrees. So, in 3 days a thinsat can move from one aperture to the next, and in 52 days it can move anywhere in the m288 orbit.
