What network design is used to communicate between the satellites? I presume that they don't all go at the same speed in the same direction, so the network layout must be flexible, right?
Also, what is their size? You called them nanosatellites, can they really be a hundred nanometers big? How are they powered, and how are they put out of commission?
Ah yes! I think the term "nanosatellites" is a bit confusing--it refers to satellites between 1 and 10 kg (https://en.wikipedia.org/wiki/Miniaturized_satellite#Nanosat...). Ours are 3U cubesats so they are about 30cm long. Much bigger than a hundred nanometers!
They have solar panels which are used to charge batteries, and since they are in low-earth-orbit they will eventually de-orbit and burn up on reentry after several years. The FCC actually requires that cubesats re-enter the atmosphere within 25 years.
