通过建立 SINS/GPS/BDS/EC 联邦卡尔曼滤波器,引入遗忘因子的自适应滤波算法,以解决常规滤波发散问题,提高组合导航定位精度。仿真分析,相对于常规滤波,带有遗忘因子的自适应滤波对于滤波发散现象起到了明显控制作用,体现出了较高的精度和较强的鲁棒性。
通過建立 SINS/GPS/BDS/EC 聯邦卡爾曼濾波器,引入遺忘因子的自適應濾波算法,以解決常規濾波髮散問題,提高組閤導航定位精度。倣真分析,相對于常規濾波,帶有遺忘因子的自適應濾波對于濾波髮散現象起到瞭明顯控製作用,體現齣瞭較高的精度和較彊的魯棒性。

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 .
