Abstract

Abstract: This paper analyzes the performance of static and kinematic PPP of combined GPS,GLONASS,Galileo,BDS-2,BDS-3 and QZSS with global 100 stations evenly distributed. The results show that multi-system fusion greatly reduces the convergence time and improves the positioning accuracy. The average convergence time of horizontal, vertical and three-dimensional components of GPS-only and six-system fusion static PPP is 18.5, 18.0, 19.0 min and 11.5, 12.0 and 12.5 min, respectively, and the one-hour positioning accuracy is 1.9, 2.2, 2.1 cm and 1.2, 1.5 and 1.4 cm, respectively. The average convergence time of horizontal, vertical and three-dimensional components of GPS-only and six-system dynamic PPP is 34.5, 33.5, 36.0 min and 15.0, 15.5 and 16.5 min respectively, and the positioning accuracy after convergence is 1.9, 2.6, 2.3 cm and 0.9, 1.6 and 1.3 cm respectively.

Key words: six systems integration, static and dynamic precise point positioning, positioning accuracy, convergence time
