基于Vondrak滤波的GPS周跳探测与修复

APPLICATION OF VONDRAK FILTERING DETECTING AND REPAIRING GPS CYCLE CLIPS

利用天文数据处理中的最优平滑法Vondrak滤波,导出了结合双差观测数据的GPS周跳探测与修复的新方法,实现了分析双差观测数据质量和双差观测域中探测和修复周跳的功能。

T Vondrak filtering is used to analyze the residual of double- difference ,and then a new method for detecting cycle slip together with Vondrak filtering is proposed. The method was tested to be very useful in detecting and repairing cycle slips and analyzing the quantity of observation data.
