For the communications problem, the idea is to use three dimensional phased arrays of thinsats—basically a bunch of satellites in a large block working in unison to generate a specific signal, behaving as if they were a much larger antenna. This is tricky and requires precision timing and exact distance information. The array’s physical configuration will need to be randomized (or perhaps arranged according to an optimized pattern) in order to prevent grating lobes, a problem with interference patterns that is common with phased arrays. They would link with GPS and each other by radio on multiple bands to achieve “micron-precision thinsat location and orientation within the array”.
Sounds like a good application for that vortex radio thing that basically only works in freespace.
