摘要
为扩展双星导航定位系统的应用范围,针对双星导航系统双星定位时用户的有源问题提出了一种无源导航定位方法,用户不必发射导航定位请求信号,直接接收就可完成定位.同时,结合差分技术来提高用户导航的定位精度.通过理论分析和仿真,说明该方法是可行的.
A passive positioning way is proposed, by which the user can get the positioning information without sending any signal. Difference technology is adopted to improve the navigation precision as well. At last, this way is proved to be effective by the theoretical analysis and simulation.
