摘　　要：Sage-Husa滤波和强跟踪滤波是2种常规的自适应卡尔曼滤波,有各自的优缺点。综合2种滤波的特点,给出一种抗粗差的修正算法,实验效果比较好,能有效抑制少部分粗差带来的影响,计算结果表明效果比较理想。Sage-Husa adaptive filtering and strong tracking adaptive filtering are two general adaptive Kal man filters, but they both have advantages and disadvantages. The paper proposes an approach to anti gross error correction algorithm by combination of the fliers above based on the filter divergence analysis.Experimental results were quite good and can inhibit the small impact of gross errors.
