Space Applications of GPS

G. B. Green, P. Axelrad

Abstract:	The country's space systems ground command and control network is rapidly becoming antiquated, and will not be able to handle the expansion of space traffic projected in the 21st century. There is a heavy reliance on vulnerable overseas ground locations which are not guaranteed. A cooperative satellite system architecture based on GPS would significantly alleviate the complexity of a future command and control structure. Specifically, if each satellite were to carry a GPS receiver as part of its telemetry tracking and command subsystem, all space vehicles could maintain accurate time, ephemeris, and attitude estimates. The commonalty of the system to all users would permit the operation of a time division multiple access system such that the ground monitoring function would be reduced to merely reviewing the telemetered data.
