| 摘 要： | 由于"北斗"定位卫星数量的限制,接收机在动态定位的精度上会出现较大的误差.针对这一问题,提出采用描述载体运动的"当前"统计模型,建立北斗无源动态定位卡尔曼滤波模型.针对可能导致滤波发散的"野值",提出将χ2:检验法与新息加权法相结合的处理方法.通过跑车实验,验证了建立的模型能很好的改善定位的精度及动态性能.

| Abstract: | Since the quantity of the "BeiDou" satellite is limited,the precision of the result is low in passive dynamical measuring process. Based on "CA" statistical model,residual test method combined with weighted innovation to remove the outlier. From the real-time experiment,the results show that this filter model can improve the precision and the dynamical performance. |
