In micro-electro-mechanical system based inertial navigation system(MEMS-INS)/global position system(GPS) integrated navigation systems, there exist unknown disturbances and abnormal measurements. In order to obtain high estimation accuracy and enhance detection sensitivity to faults in measurements, this paper deals with the problem of model-based robust estimation(RE) and fault detection(FD). A filter gain matrix and a post-filter are designed to obtain a RE and FD algorithm with current measu...
