摘      要：The rapid development of intelligent navigation systems has speed development for its uses in military and civilian applications. On-board integrated navigation and multiple sensors are essential for real-time data update. Using multiple sensors may sever from the disconnection of the readings due to sensor(s) transient faults. So, the need for sensor(s) transient fault correction becomes an important action to improve performance. In this study, a novel proposed optimal pseudo sensor enhancement method (OPSEM) is introduced, investigated and implemented. The proposed OPSEM has multiple missions: (i) optimal arrangement for the sensors architecture, (ii) detecting, isolating, and compensating for the sensor(s) transient fault. The simulation results of the traditional and the proposed OPSEMs for multiple sensor architecture have been obtained, analysed and compared. Also, the proposed OPSEM has been applied to the proportional navigation guidance law to check for the improved performance. Finally, the integrated OPSEM navigation system has been realised and implemented. The proposed OPSEM practical system has been examined using unmanned aerial vehicle and fixed wing aircrafts to illustrate the improved operation of the proposed OPSEM system.
