RUBIDIUM AND CESIUM FREQUENCY STANDARDS STATUS AND PERFORMANCE ON THE GPS PROGRAM

M. Van Melle

Abstract:	The evolution of the frequency standards on the GPS program started with the Block I concept validation program, beginning with a proposal program in 1973 and followed by the (CPS I through 8) prototype space vehicle contract in 1974. The full-scale developmental (GPS 9 through 11) models contracted in 1978 provided both navigation and nuclear detection capability. The production qual vehicle (GPS 12) was contracted in 1980, and the production vehicles (GPS 13 through 40) were contracted in 1982.
