| Abstract: | Reliability is very important to civil aviation except for precision. Integrated navigation technology can greatly improve navigation system accuracy . Real-time fault detection for integrated navigation system can effectively improve navigation system reliability. This paper researched on the tightly coupled IRS/GPS Integrated arithmetic based on the residual chi-square fault detection. In order to validate the performance of the arithmetic, simulation and analysis are carded out. The simulation result indicates that integrated navigation and fault detection can effectively isolate GPS failure measurement and maintain high position accuracy and improve the reliability of the integrated navigation system. |
