Evaluation of daily jump compensation methods for GPS carrier phase data

In this paper, we described the timing-offset comparison results between various daily jump compensation methods for GPS carrier phase measurement data. For the performance comparison, we used about 70 days GPS measurement data obtained from two GPS timing receivers which share the reference 1 PPS and RF signals and closely located in each other within a few meters. From the experiment results, it is observed that clock bias can be occurred in the case of using a simple compensation method accumulating daily jumps with non-perfectly estimated jump values.
