Zhuang Liang-jie · Journal of Chinese Inertial Technology · 2002
Based on a deep investigation, a multiple model adaptive estimation method for stochastic systems is dealt with in this paper, and it is applied to INS/ESGM integrated navigation system. Comparing the performance of single model INS/ESGM integrated navigation system with that of multiple model INS/ESGM integrated navigation system by digital simulation, it is showed that introducing multiple model adaptive estimation theory into INS/ESGM integrated navigation system can enhance the adaptability of system scheme to the environment and greatly improve the accuracy of integrated navigation system.
