  • With the ability of providing Real-Time Precise Point Positioning (RTPPP) service for China and surrounding countries, the application of BeiDou Navigation Satellite System(BDS-3) PPP-B2b signals have seen a rapid rise in recent years. And the performance evaluation is a vital issue for large deployment in the future, such as the evaluation about the accuracy of orbit and clock error, as well as the analysis of precision and convergence time for Precise Point Positioning(PPP). We hereby follow this idea in this paper. Based on the September observations of the China branch stations of international GNSS Monitoring and Assessment System(iGMAS), the accuracy of orbit and clock error, as well as the positioning accuracy of B1I+B3I and B1C+B2a signal combination are carefully evaluated in this dissertation. The results show that the average accuracy of PPP-B2b orbit products in R, A and C direction is 0.1 m, 0.31 m and 0.3 m, respectively. Besides, the root mean square (RMS) of clock error correction is 2.26 ns, In terms of PPP convergence, the B1I+B3 signal combination using GBM products is the quickest among them, with the highest final convergency accuracy. The second is B1I + B3I (PPP-B2b), and B1C + B2a(PPP-B2b) is at the last. Summarizing the above discussions, BDS-3 PPP-B2b signals is capable of providing regional PPP service in China.
