| Abstract: | According to the fault types and characteristics of an integrated navigation system, a new fault detection method based on signal processing is addressed. This new method analyzes and processes the system signal that contains fault information by use of the wavelet technology. It has been applied in the SINS/GPS integrated navigation system. The simulation result shows that the wavelet analysis technology can detect the abrupt fault efficiently, and is more simple and agile. Therefore, the wavelet analysis technology could be used for fault detection of an integrated navigation system. |
