GPS载波相位观测值中周跳探测的研究

The Research on Cycle-slip Detection of GPS Carrier Phase Observable

在GPS测量数据处理中,如何对载波相位观测值中的周跳进行探测和修复是精密定位数据处理中的一个十分重要的问题。本文介绍了几种周跳探测的方法,并且实际数据证明基于小波变换的周跳探测自动化程度较高,定位准确,在实际应用中具有较高的实用价值。

During the GPS data processing, how to detect and repair the cycle - slip in the carrier phase observable is an important problem. This paper introduce several methods of cycle - slip detection. The true data validate that the cycle - slip detecting based on the wavelet transformation has the higher degree of the automatization and the exacter position, so this method has highly useful value in the real application.
