摘　　要：指出了在组合导航系统中，Ｋａｌｍａｎ滤波器的预测周期与滤波周期之间的异步性会给滤波器的动特性带来不良影响。针对这一问题，提出了一种修正Ｋａｌｍａｎ滤波算法，并将其应用于高精度定位定向系统的“惯性／位置”组合导航中。In integrated navigation systems, the asynchronism between Kalman filter′s predicting period and the filtering period is pointed out to have a bad influence on the dynamic behavior of Kalman filter A modified Kalman filtering algorithm is presented to deal with this influence and is applied to the integrated navigation of a locating and directing system with high precision
