摘　　要：近年来随着全球导航卫星系统的发展,多种导航卫星系统的组合使用成为卫星导航领域的一个研究热点。文章提出由导航系统与通信系统相融合的设计思想,以北斗(简称BD)导航定位系统与全球星系统融合为例,分析融合系统的定位性能。着重从可见星数目和GDOP的角度对定位精度进行仿真分析,与单纯的BD导航定位系统的定位精度对比,得出融合系统定位精度更高、性能更好的结论。With the development of global navigation satellite systems in recent years, integration of multiple navigation satellite systems gradually becomes a hot spot. In this paper we study the performance of integrated system of satellite com- munication system and navigation satellite system. Taking an example of integrated system of Compass and Globalstar, this paper analyzes the positioning accuracy from the point of visible satellite number and GDOP. A conclusion is drawn that the performance of integrated system is better than that of Compass navigation system.
