ZHAO Wang-yang~1, YANG Gong-liu~2, ZHUANG Liang-jie~2. Study on multi-model Kalman filter of multi-navigation sensors[J]. 2006, (7): 85-88. DOI: 10.13873/j.1000-97872006.07.028.
Multi-model adaptive estimation method is applied to data fusion of the intenerated navigation system.Comparing the single model performance of inertial navigation system(INS)/global position dystem(GPD)/Doppler log integrated navigation system with that of multi-model adaptive estimation integrated navigation system by digital simulation
multi-model electric filter is satisfactory for stable filter.Multiple model adaptive estimation system can enhance the adaptability of integrated navigation system scheme to the environment and can greatly improve the accuracy of integrated navigation system.
