Abstract:	The rubidium clock used in the GPS Block IIR space vehicles is a design that had not flown previously in space. A long-term life test of two of these clocks is being conducted in the Clock Test Facility of the Naval Research Laboratory (NRL) to gain information on their reliability and operating characteristics. Data is presented showing the design of the test, the clock performance, and typical behavior of several of the clock telemetry parameters. The performance of the clocks under test is compared with the on-orbit performance of the rubidium clock on Navstar 43—the first operational Block IIR space vehicle.
