The main analysis is the Sage-Husa adaptive Kalman filter. With improved methods of system noise and measurement noise variance estimation in the filtering process, the divergence phenomenon in Sage-Husa adaptive filter is restrained. Through analysis on comparison with the result of Kalman filter, the effect of the improved adaptive filter was tested. Based on experiment and simulation, the improved adaptive filter precision was improved, and the divergence phenomenon of improved adaptive filter didn't appear.
Key words： adaptive filter; filter divergence; integrated navigation; Kalman filter
