On-Orbit Frequency Stability Analysis of the GPS (Global Positioning System) NAVSTAR's 3 and 4 Rubidium Clocks and NAVSTAR's 5 and 6 Cesium Clocks,

Abstract

This paper describes the on-orbit frequency stability performance analysis of the GPS NAVSTARs 3 and 4 rubidium clocks, and the NAVSTARs 5 and 6 cesium clocks. Time-domain measurements, taken from the four GPS monitor sites, have been analyzed to estimate the short- and long-term frequency stability performance of the NAVSTAR clocks. The data analyzed includes measurements from 1981, 1982, and the first 100 days of 1983. Short- and long-term results are presented for data collected during 1982. The Allan variance was used as the measure of frequency stability performance in the time domain. (Author)
