摘要/Abstract

摘要： 本文基于全球均匀分布的100个测站分析了GPS、 GLONASS、 Galileo、BDS-2、 BDS-3和QZSS六系统融合静态和动态PPP定位性能。结果表明:多系统融合极大地减少了收敛时间,提高了定位精度。单GPS和六系统融合静态PPP水平、高程和三维分量平均收敛时间分别为18.5、18.0、19.0 min和11.5、12.0、12.5 min,1 h定位精度分别为1.9、2.2、2.1 cm和1.2、1.5、1.4 cm。单GPS和六系统融合动态PPP水平、高程和三维分量平均收敛时间分别为34.5、33.5、36.0 min和15.0、15.5、16.5 min,收敛后定位精度分别为1.9、2.6、2.3 cm和0.9、1.6、1.3 cm。

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
