一种新的GPS静态多路径削弱方法

A New Method for Mitigating Kinematics Multi-path Effect

多路径误差是GPS的重要误差源之一。本文介绍了多路径效应产生的原理,归纳比较了目前国内外多种关于多路径误差的处理技术,论述了多路径效应的数学模型及其特性,提出一种通过移动平均来削弱GPS静态多路径的方法,通过实测数据进行分析,验证了其正确性。

Multi-path effect is a major error source of GPS.This paper describes the principle of multi-path effect,gives the summarizations and comparison of the existing mitigating technology for multi-path effect at home and abroad,and discusses the mathematical model and characteristics of multi-path effect.The authors propose a method for mitigating the multi-path effect using moving average.Through the analysis of measured data,its correctness is verified.
