This paper uses particle filter(PF) to solve the nonlinear problems in integrated navigation.The characteristic and general modelling methods for the filtering model are summarized based on typical problems in nonlinear filtering of integrated navigation.From the framework of PF algorithm,the characteristics and improved measures about PF are achieved.According to the characteristics of data processes in integrated navigation,the rules for selecting the appropriate PF algorithms are given to resolve the problems.The experiments show that the optimized measures about PF and the modelling methods about nonlinear filtering could effectively solve the nonlinear filtering problems in integrated navigation system.
