摘要
针对目前北斗双星系统在军事应用方面受到限制的问题,提出采用伪卫星辅助增强双星系统方案实现特定区域内无源定位。分析采用一颗伪卫星时系统的视距范围,并在视距覆盖范围内对"双星+1颗伪卫星+高度表"的定位方案的定位误差参数进行仿真。仿真结果表明:采用伪卫星来辅助增强北斗双星系统,可提高系统应用的隐蔽性,增强系统的军事应用价值。
Aimed at the limitation of the Beidou double-star system＇s military application value, a local passive position scheme was put forward by using imitate satellite aided to aid Beidou double-star system. The sight-distance range of one imitate satellite aided was analyzed. The location error arguments of the passive position method of ＂double-star ＋ one imitate satellite aided ＋ altimeter＂ within the sight-distance were simulated. The simulation results show that this scheme is feasible, which can enhance the security and the military application value of the system.
