| 摘 要： | 为了解北斗三号系统在国内外及南北极地区的定位性能,在STK仿真平台下建立了北斗三号系统30颗星(3GEO、3IGSO和24MEO)的星座模型,对北京、三亚、新加坡、南北极点等11个站点的平均可见星数和几何精度因子GDOP值进行了分析,并与GPS进行了对比。结果表明,北斗三号系统较GPS在国内外及南北极地区典型站点的定位性能更优。

| Abstract: | Aiming to master the positioning performance of BeiDou-3 system (BDS-3) at domestic,foreign as well as south and north polar regions,the simulation platform named Satellite Tool Kit(STK) is used to construct the BDS-3 constellation(24 MEO,3GEO and 3IGSO)model.The mean number of visible satellites and GDOP values are analyzed at 11 stations such as Beijing,Sanya,Singapore,south and north polar points compared with the GPS.The results show that the BDS-3 has a better positioning performance than GPS at these stations. |
