Long-Term GPS Carrier-Phase Time Transfer Noise: A Study based on Seven GPS Receivers at NIST

Abstract

This paper reports a preliminary study of the long-term GPS carrier-phase time transfer noise, based on seven NIST GPS receivers. It shows that the carrier-phase time-transfer result using one receiver can typically be ~ 0.5 ns (peak-to-peak) different from that using another receiver, over 100 days. For an extreme situation, the time-transfer difference between two receivers can be as large as ~ 1.3 ns (peak-to-peak) during 100 days. This suggests that a more frequent GPS calibration is needed to achieve sub-nanosecond GPS timing accuracy.
