Abstract
A Telemetry, Tracking and Control (TT&C) system for a satellite cellular communication system utilizing one of the user voice/data communication channels to communicate TT&C data with a satellite and through one satellite to other satellites. A Global Positioning Receiver (GPS) on board each satellite provides position control signals to the on board satellite control subsystem and the GPS receiver communicates ephemeris information to a ground station through the cellular user data channel. The system allows for constant TT&C communication to and from a mobile ground station and to and from any satellite.
