In order to analyze the pseudo-single-point positioning accuracy of BDS2, BDS2 /BDS3, the two methods are used to solve the BJF1, BRCH, SHA1, ZHON, CHU1, DWIN stations from 298 days to 304 days in 2018. Count. By comparing the changes of PDOP value and visible satellite number in one day of the two positioning modes, as well as the vertical deviation, horizontal deviation and three-dimensional deviation of one week, the accuracy of single-point positioning of B1I single-frequency pseudo-range . The experimental results show that the positioning accuracy of both modes is within 10m. The BDS2/BDS3 is better than BDS2 positioning, and the positioning accuracy is improved by 4%-28%.
