Evaluation of Carrier-Phase GNSS Timing Receivers for UTC/TAI Applications

Abstract : USNO evaluated several carrier-phase GNSS timing receivers to determine their suitability to support UTC/TAI applications. These receivers were subjected to thermal testing, power cycle retrace testing, and long-term stability evaluation. The goal is to identify candidate replacement receivers for the USNO to be used for UTC/TAI applications, including the common-view technique for both GPS and GLONASS monitoring. Test results are reported in this paper.
