Abstract：Aiming at the problem of conventional filter divergence ,this paper advises to construct SINS/GPS/BDS/EC federal kalman filter and introduces adaptive filtering algorithm of forgetting factor so as to improve integrated navigation po‐sitioning precision .The simulation shows that the adaptive filtering with forgetting factor controls the filter divergence phe‐nomena obviously relative to conventional filtering ,embodies higher precision and strong robustness .
