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. 

关 键 词:GEO  BDS-3  伪距单点定位  精度

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%.
