多路径误差对GPS精密定位的影响
The impact of multipath errors on GPS precise positioning
摘要
Abstract
M ultipath error ,w hich is one of main source errors in GPS precise positioning ,is also one of the most difficult errors to deal with .Greatly reduce or eliminate multipath errors can ef‐fectively improve accuracy of GPS precise positioning .Firstly ,the formula of multipath error is derived in this paper .T hen the impact of different t factors such as dilution factor ,reflecting dis‐tance ,the height of GPS receiver and reflection coefficient on multipath error of GPS signals is studied .The influence of multipath error caused by several different factors on GPS precise posi‐tioning is obtained ,and corresponding methods for reducing multipath errors is presented .关键词
