基于双频载波相位求差法进行GPS周跳探测

GPS Cycle Slip Detection Method Based on Dual Frequency Carrier Phase Difference Method

随着GPS广泛应用于高精度定位测量,周跳探测已经成为GPS研究的热点。针对双频载波观测值的特点,通过相邻历元的相位观测值求差来探测周跳,并通过实例证明该方法可以有效地进行周跳探测。

With the increasing use of GPS in high-precision positioning measurement,cycle slip detection has become a hotspot in GPS research.In this paper,according to the characteristics of dual frequency carrier observation,the phase jump was detected by the phase observation of adjacent epochs.The method was proved to be effective.
