摘　　要：为掌握北斗区域和GPS组合系统在国内典型地区的定位性能,利用STK软件建立了北斗区域和GPS组合系统星座,在此基础上对北京、昆明、漠河、武汉、拉萨、乌鲁木齐、曾母暗沙等站点的卫星可见性和几何精度因子进行了仿真分析。研究表明北斗区域和GPS组合系统定位性能相比单系统有显著提高,可满足高精度导航定位需求。In order to master the positioning performance of combined BeiDou regional and GPS satellite systems,their constellations are simulated using STK software.Based on this simulation,the satellite visibility and Geometric Dilution of Precision value in some typical regions such as Beijing,Kunming,Mohe,Wuhan,Lhasa,Urumqi and James Shoal are systematically analyzed.The research indicates that the positioning performance of combined BeiDou regional and GPS satellite systems are greatly improved compared to the single BeiDou or GPS,which could satisfy the high precision requirement of navigation and positioning.
