Rubidium and Cesium Frequency Standards Status and Performance on the GPS Program

Harry Bethke, Dale Ringer, M. Van Melle

Abstract:	This paper describes the on-orbit operational performance of the frequency standards on the GPS 1-10 Navstar satellites. The history of the Rb frequency standards showing the improvements Incorporated at various stages of the program and the corresponding results are presented. Also presented is the operational history of the Navstar Cesium Frequency Standards. The frequency standards configuration data presented will cover the chronology of even i.s from the concept validation satellites, Navstars 1-10, starting in 1978 to the present, including the configurations of clocks to be used on the GPS Production Program, Data will be presented additionally showing the results of long-term laboratory testing of a production Rb frequency standard with the necessary data taken to calculate Delta P, drift, time error, and Allan variance,
