摘　　要：自适应选权滤波的思想是通过对状态参数进行分类,构造等价权,进行有效遏制载体状态异常。本文在对观测信息抗差估计和状态信息自适应估计基础上,进行了GPS/BD组合导航定位。试验表明:基于抗差自适应选权滤波的GPS/BD组合导航可以有效抑制观测与状态异常,提高导航定位精度。The thought of selecting weight filtering is through classifying the state pa-rameter to construct equivalent weight to resist errors of kinematic models .The GPS/BD satellite navigation based on robust adaptive selecting weight filtering is done in this paper . T he results show that this method can control outliers of model an improve accuracy of navi-gation .
