摘要:
当精密单点定位的观测值含有异常数据时,Kalman滤波的精度将会降低。采用抗差Kalman滤波方法能够有效抑制观测异常,提高滤波的精度和可靠性。运用武汉国际GPS服务跟踪站数据对该方法进行了验证。结果表明,抗差Kalman滤波的精度比Kalman滤波的精度有一定程度提高,说明抗差Kalman滤波能够有效抑制观测异常。
Abstract:
If the outliers exist in the observations, the accuracy of Kalman filtering will be lower. Robust Kalman filtering, which can improve the precision and the reliability of Kalman filtering, is used to control the outliers. The data from the tracking station of International GPS service in Wuhan are computed to test the efficiency of Robust Kalman filtering. The results show that the precision of Robust Kalman filtering is better than Kalman filtering, and it can control efficiently outliers in the observations.
