BDS和GPS导航系统亚太地区定位性能分析

摘要

通过仿真在轨的北斗卫星和GPS卫星，利用STK覆盖功能分析北斗、GPS和北斗/GPS组合导航系统在亚太地区的定位性能，并比较北斗/GPS组合卫星导航系统与单系统相比的优势。仿真结果表明北斗/GPS组合卫星导航系统在亚太地区有更好的可用性，能提供更高精度的导航定位服务。%The working BDS and GPS satellites are simulated in this paper. The performance of BDS,GPS and BDS/GPS integrated navigation system is analyzed by using STK coverage tools. The result shows that BDS/GPS integrated navigation system has a better availability and it can provide more precise poisoning service.
