针对惯性导航系统故障维修时间长的问题，提出了采用卡尔曼滤波器估计系统内部状态和参数，采取z。检验法来确定系统量测信息的有效性的方法，给出了滤波器设计需要的系统状态参数。在某型惯性导航系统故障维修中验证了通过采用卡尔曼滤波器对系统内部参数进行估计，可以提高故障诊断的效率。
針對慣性導航繫統故障維脩時間長的問題，提齣瞭採用卡爾曼濾波器估計繫統內部狀態和參數，採取z。檢驗法來確定繫統量測信息的有效性的方法，給齣瞭濾波器設計需要的繫統狀態參數。在某型慣性導航繫統故障維脩中驗證瞭通過採用卡爾曼濾波器對繫統內部參數進行估計，可以提高故障診斷的效率。

To improve the testability of INS and decrease the fixing time of INS Fault, this paper proposed maintenance method based on inner states estimate with Kalman filter and evaluating of measure information with two chi-square test. The system state were introduced which were needed in filter. It also proposed a fault-tolerant integrated navigation system with two INS,GPS and log to improve the testabili ty. With a instance of INS maintenance, it is proved that the estimate of the system inner parameter with kalman filter can effectively support the fault diagnosis of INS.
