Abstract: A GPS time transfer receiver developed by the Naval Research Laboratory has been provided by the GPS Program Office to Rockwell International in Anaheim, California, to perform clock measurements and analysis. The receiver performs time measurements between GPS satellite clocks and a ground clock. The measurements are referenced to the GPS Master Clock and also to the Naval Observatory Master Clock (UTC(USN0 MC)) using data transmitted by the satellites. Measurements were made over a period of a year using the laboratory cesium standard at Rockwell as the ground station clock. A phase plot was kept relative to the Naval Observatory UTC and stability analysis of the clock was performed using the data. The measurement results of the time comparison had an RMS less than 100 ns and the frequency stability as compared againps the USN0 ensemble was on the order of parts in 10 over a one day period.
