中文摘要：
GPS测量经常会受到接收机周围环境的影响,其中最为显著的是多路径效应。因此,消除多路径误差是一个急需解决的问题。本文研究了利用信噪比来改正多路径误差的方法,且利用VB编程软件实现了其程序的编写,最后通过对实验数据的计算,验证了该程序的可行性,达到了对多路径误差改正的目的。
英文摘要：
The environment of GPS receiver affects GPS surveying and the biggest influence is multipath effect. Therefore,it is a problem for us to solve urgently. In this paper,an algorithm that makes use of signal noise ratio （SNR） to correct multipath error is studied,and corresponding software is implemented by using Visual Basic （ VB）. In the end,the software is validated by experiment data. In a word,the algorithm and software are very useful for mending multipath error.
