    Abstract
  • Since the BeiDou Navigation Satellite System (BDS) has been formally networked, it is necessary to evaluate and analyze the positioning performance of the BDS. This article mainly through 5 days observation data from 8 stations in MGEX (Multi-GNSS Experiment), give priority to with BeiDou-2/ BeiDou-3 (BDS-2/BDS-3) to analysis BDS-2/BDS-3, BDS-2/BDS-3/Galileo, BDS-2/BDS-3/GPS, BDS-2/BDS-3/GPS/Galileo four different combination of satellite system static precise point positioning (PPP) performance, the experimental results show that the positioning accuracy and convergence speed of BDS-2/BDS-3 static PPP in east (E), north (N) and up (U) directions are better than 2.49 cm, 2.27 cm, 4.04 cm and 34.6 min, 19.3 min and 28.1 min, respectively. The positioning accuracy and convergence speed of BDS-2/BDS-3/GALIEO static PPP in E, N and U directions are better than 1.81 cm, 1.65 cm, 2.94 cm and 20.4 min, 13.0 min, 18.6 min, respectively. The positioning accuracy and convergence speed of BDS-2/BDS-3/GPS static PPP in E, N and U directions are better than 1.67 cm, 1.62 cm, 2.82 cm and 18.3 min, 10.2 min, 16.1 min, respectively. The positioning accuracy and convergence speed of BDS-2/BDS-3/GPS/Galileo static PPP in E, N and U directions are better than 1.46 cm, 1.40 cm, 2.45 cm and 14.5 min, 9.3 min, 14.5 min, respectively.
