GPS动态测量连续周跳检验

本文针对ＧＰＳ动态测量中经常出现的连续周跳,提出了一种新的连续周跳的检验方法。该方法在理论上是最优的,与Ｋａｌｍａｎ滤波平行操作,能够实行处理周跳引起的偏差;而且,在偏差估计的同时,兼顾后续偏差检验,因而可利用尽可能多的观测历元信息来获取精度较高的偏差估值。实例计算表明,该方法在应用中是很有效的。

Detection of Successive Cycle Clips for GPS Kinematic Positioning

In this paper a new procedure for detection of successive cycle slips is developed by which the biases at measurement epoch can be detected considering the estimates of a priori biases. The method is proved to be optimal, and it can be performed parallel to the Kalman filtering. The biases due to the cycle slips can be detected in real time. The method can utilize more information than existing procedures in evaluating the biases. An example is given and shows that the method is effective and reliable
