CHENG Hong-bing, HUANG Guo-rong, LIU Hua-wei. Summary on fault detection and diagnosis for navigation systems[J]. 2010, 29(3): 1-4. DOI: 10.13873/j.1000-97872010.03.011.
The theoretical field pay extensive attention to fault detection and diagnosis(FDD) for navigation system.Methods of FDD for navigation system are summarized at home and abroad.They are based on hardware redundancy method
based on χ2 test method
based on parity space method
based on wavelet transform method
based on neural network method
based on federated filter method and some other methods.Future development trend in this field is discussed.
