Abstract:In this paper, we analyze observation data collected from iGMAS and MGEX reference stations based on the self-written data processing algorithm. The result indicates the outstanding performance of Beidou new signals. In the aspects of data integrity rate and signal-to-noise ratio, BDS-3 signals are weaker than GPS. In terms of the multipath error and pseudorange noise, BDS-3 signal is at the same level as GPS. Regarding ionosphere delay rate, BDS-3 signals are better than GPS. On the whole, the performance of Beidou-3 is equivalent to that of GPS.
