Abstract

Aiming at the difficulty of fault detection in integrated navigation system using multi-sensors, wavelet technology is used to analyze sensor's signal state. It can find fault point in a short time, which makes the system work in real time. Federal information fusion mechanism and fuzzy method are used to switch between normal system and fault system without harass, realizing adaptive system reconstruction, thus the navigation localization precision, faulty tolerance and reliability capability is guaranteed. Road test and computer simulation are combined to validate the proposed scheme. The feasibility is tested.
