1. A system of communication comprising at least one fractionated satellite, the fractionated satellite comprising a main satellite and a plurality of ancillary satellites, wherein:
the main satellite and the plurality of ancillary satellites communicate with user equipment on a surface of the earth with uplink and downlink communication links having communication frequencies in the range of 0.1 to 40 GHz, and
distances between the satellites exceed several tens of wavelengths of the communication wavelengths associated with the communication frequencies, and
wherein the main satellite and the plurality of ancillary satellites communicate among themselves through a plurality of intersatellite links whose transit delays are measured by adding time stamps to message packets shared between the main satellite and the plurality of ancillary satellites, wherein the time stamps are synchronized to global positioning system (GPS) time.
