RUBIDIUM FREQUENCY STANDARD TEST PROGRAM FOR NAVSTAR GPS

Frank K. Koide, Darrell J. Dederich

Abstract:	Space-qualified Rubidium Frequency Standards (RFS) are being developed for the NAVSTAR Global Positioning System (GPS) program by Rockwell International Electronic Systems Group. This paper will present the test data of the RFS Program in the Production Phase and computer automation as an essential element in the evaluation of the RFS performance in a simulated spacecraft environment. Typical production test data will be discussed for stabilities from 1 to 100,000 seconds averaging time and simulated time error accumulation test. Also, design considerations in developing the RFS test systems for the acceptance test in production will be discussed in the paper. Finally, as part of a life-cycle test in vacuum, stability data to 1,000,000 seconds averaging time will be presented.
