Abstract:

This report describes the on-orbit frequency stability performance analysis of the Global Positioning System 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 presented include measurements from 1981, 1982, and the first 100 days of 1983.
