| description | An overview of the Global Positioning System (GPS) constellation with respect to the lifetimes of space vehicles and space vehicle clocks, both active and deactivated, is presented. Analysis of clock performance with respect to frequency stability is reviewed. The operational Navstar timing signals are ranked according to frequency stability for a sample time of 1 day. In addition, the performance of the Block IIR clocks is compared to that of two flight-qualified Block IIR rubidium atomic frequency standards undergoing life tests in the NRL Precision Clock Evaluation Facility. This work was performed under the sponsorship of the GPS Joint Program Office.
