摘要: 地球静止轨道（GEO）卫星是北斗卫星导航系统（BDS）星座的主要组成部分,为分析其对北斗三号（BDS-3）定位性能的影响,本文基于MGEX跟踪站实测数据,分析了GEO卫星对BDS-3伪距单点定位精度的影响．经研究发现,GEO卫星能有效改善BDS-3卫星可见数与卫星空间几何构型,能有效提升BDS-3伪距单点定位精度,北斗二号（BDS-2）／BDS-3 GEO卫星使BDS-3伪距单点定位精度的提升量优于任一单系统GEO卫星,GEO卫星对BDS-3伪距单点定位水平向定位精度提升在30％以内,对高程方向定位精度提升在20％以内．Abstract: GEO satellites are the main components of the BDS constellation.In order to analyze its impact on the positioning performance of BDS-3,this paper analyzed the impact of GEO satellites on the positioning accuracy of BDS-3 pseudorange single point based on the measured data of MGEX tracking station.The research found that the GEO satellite can effectively improve the BDS-3 satellite visible number and satellite space geometry,and can effectively improve the BDS-3 pseudorange single-point positioning accuracy.The BDS-2／BDS-3 GEO satellites make the BDS-3 pseudorange single-point positioning accuracy better than that of any single-system GEO satellite.The horizontal positioning accuracy of BDS-3 GEO satellites pseudorange single-point positioning is improved within 30％,and the positioning accuracy for elevation direction is improved within 20％.
