Implementation and Comparison of Time and Frequency Transfer Methods by GPS Carrier Phase

Abstract

Nowadays, GPS carrier-phase time and frequency transfer methods are applied more and more in the timing area because of their high ranging resolution, which corresponds to high time and frequency transfer precision. In this paper, we have built a GPS carrier-phase time and frequency transfer system preliminarily at the National Institute of Metrology (NIM). Several different time and frequency transfer experiments, including zero-baseline and long-baseline experiments with the same reference or the different references, conducted using GPS carrier phase with the GPS carrier-phase time and frequency transfer system by two different solution methods, were implemented and the experimental results are compared.
