摘　　要：双星定位系统是中国建立起来的一种区域性全球定位系统(RDSS)。文章分析了双星定位系统存在的不足,提出了在双星定位系统上基于三颗地球同步卫星的三星定位导航系统,接收机可以根据测得的三个伪距以及高度表信息解算用户位置。进一步研究了三星定位系统与SINS进行伪距方式组合的导航系统,仿真结果表明了该组合导航系统可有效地提高定位精度,是一种非常适合于中国国情的惯性/卫星组合导航系统。Double star navigation system is one regional global navigation system (RDSS) built up by our country. The disadvantage of Double star navigation system is given and one navigation system made up of three earth synchronous satellites based on Double star navigation system is put forward. The receiver can calculate the position of user according to the three measured pseudo ranges and the altimeter's message. And the integration navigation system of Three star navigation system and SINS based on pseudo range are further studied. The simulation results show that this integration method can improve the navigation precision effectively, and is one kind of inertial/satellite integration navigation system fit for our country.
