The Stability of GPS Carrier-Phase Receivers

Lee A. Breakiron

Abstract:	GPS carrier-phase (CP) time and frequency transfer is a convenient and reliable method to compare distant ground clocks. Short- and long-baseline experiments were performed to ascertain whether CP receivers are sufficiently stable for use in the calibration of Two-Way Satellite Time and Frequency Transfer equipment and the comparison of primary frequency standards. The results were affirmative, demonstrating a time transfer precision of about 100 ps or better in a few days over short baselines and about 100 ps at 1 day and about 300 ps at 5 days over long baselines, provided the receivers hold their calibration, are operated under environmentally controlled conditions, and are connected to phase-stable antenna cable.
