GPS/INS Adaptive Filtering Considering the Influences of Kinematic Model Errors

An adaptive filtering for GPS/INS integrated navigation is designed,considering the influences of stochastic errors.An improved BP neural network learning algorithm is set up,on the basis of it,a new GPS/INS adaptive filtering that combines the adjustment of stochastic errors and systematic errors is put forward.The results prove that the algorithms are valid and reliable when applied in GPS/INS integrated navigation system.
