| 摘 要： | 提出了一种组合导航系统的故障诊断方法,根据不同导航子系统的特点,采用基于双状态递推器的卡方检验法、似然比检验法以及空间解析几何法分别对SINS/GPS,ADS和SINS/ADS/DME系统进行故障诊断。另外,作者利用VC实现了一套用于进行组合导航的系统故障诊断的方法,并进行了实时的诊断验证实验,其结果表明根据经验、卡方分布表以及误差标准等因素考虑选择的阈值结合相应算法的诊断准确性高,并且抗野值干扰能力强。

| Abstract: | In this paper a failure diagnoses method of integrated navigation system was proposed. According to the features of various subsystem, this method adopted the State Chi-square test, likelihood ratio test and space analytic geometry for the failure diagnosis of SINS/GPS,ADS and SINS/ADS/DME. In addition, we developed a software system for the implementation of this failure diagnosis method of integrated navigation system by use of VC, and made simulation to verify the effectiveness of the proposed method.
