BDS/INS深组合导航性能分析

通过对BDS/INS深组合导航进行较为全面的性能分析（重点针对INS辅助BDS捕获、跟踪环路机理及性能评判准则）发现，在INS辅助下可以显著提高BDS信号捕获灵敏度、缩短平均捕获时间，并可以维持环路的锁定跟踪状态以提高导航精度。同时，考虑GNSS接收机受到超强干扰或卫星信号受到持续遮挡等特殊条件，给出BDS/INS深组合的结构设计，并基于软件接收机对深组合导航系统性能进行仿真分析。该仿真结果对工程应用具有参考价值。

Performance Analysis of BDS/INS Deep Integration Navigation

BDS/INS deep integration navigation,by using INS-aided BDS acquisition and carrier tracking,has been shown to improve navigation performance under low signal-to-noise ratio and high dynamic situations. It is important to develop the research on BDS/INS deep integration navigation with application of the BDS system. In this paper, we investigate the mechanism and performance evaluation criteria in BDS/INS deep integration navigation. The deep composite structure design is given and the entire performance is simulated on a software receiver. The simulation shows that this technique is effective and useful for actual engineering applications.
