中文摘要：

本文通过对多路径效应影响进行分析，叙述了多路径效应影响分析的两个步骤，即周跳的探测与修复及多路径效应的影响分析。首先，介绍了周跳的产生、定义、来源和检验量，同时编程将其探测出来并进行了修复，得到“干净”的观测数据文件；再利用单点定位程序，求得初始坐标值，同时进行一定的平滑，得到平滑后的坐标数据；最后利用移动平均法，对静态GPS测量中的多路径效应影响进行提取，得到了更加平稳精确的坐标数据。

英文摘要：

This paper focuses on the analysis of GPS multi-path effect influence and indicates the analytical procedure of multi-path effect influence. There are two steps： the cycle slip detecting/repairing, and the multi-path mitigation. First, the definition, source, origination and test variables of cycle slips are introduced. And the ＂clean＂ observation data should get after detecting/repairing cycle slip with the special program. Then, the Precise single Poing Program （PPP） is used to have the original coordinate data and more accurate coordinate data. Finally, multi- path effects on GPS static measurement can be eliminated based on moving average method, and more steady precise coordinate data series be obtained.
