|Abstract:||BeiDou Navigation Satellite System (BDS) implemented global networking in 2020, marking that BeiDou-3 Navigation Satellite System (BDS-3) has stepped into a new era of global positioning, navigation and timing services, and it is the best time to develop and apply BDS-3 to provide quality services to users around the world. In order to analyze the performance of BDS-3 precise point positioning (PPP), RTKLIB open source program package based on the Visual Studio 2017 compilation platform is transplanted and re-developed, and the stations with the BDS-3 signal receiving capability is selected from the Multi-GNSS experiment (MGEX), in order to compare PPP performance of BDS-3/GPS, BDS-3/GLONASS, and BDS-3/Galileo integrated systems. The experimental contents included static PPP, pseudo-dynamic PPP, number of visible satellites and DOP value. The experimental results show that BDS-3/GPS integrated system has the largest number of visible satellites and the smallest Dilution of Precision value. The accuracy of three directions N, E, U (North, East, Up) after static PPP convergence is better than 5cm; PPP positioning jitter of BDS3/GLONASS and BDS-3/Galileo integrated system after convergence is larger than the BDS-3/GPS integrated system, and the convergence time is longer than BDS-3/GPS integrated system. Whether it is static or kinematic, BDS-3/GPS has the best positioning performance. It would provide a reference for the better scientific research and engineering applications of Beidou-3.|
