Progress on a New GPS Common-View Receiver

Abstract

We are developing a new GPS common-view time transfer receiver to support both International Atomic Time (TAI) and comparison of frequency standards. Our goal is to realize a time-transfer accuracy of one ns or below, and time-transfer stabilities of 0.5 ns out to 1 year. Having obtained consistent stabilities at 100 ps or below with common-clock experiments out to 1 month with three laboratory prototype systems, we are now building a unit that can be moved among different timing labs. We show studies of three different time-interval counter cards considered for this project, revealing stabilities as a function of temperature and supplied voltage.
