DGPS基准站多径误差的处理方法

An Algorithm for Multipath Error Separating in DGPS

ＤＧＰＳ是一种具有广泛应用前景的高精度导航定位系统，但其精度受多径误差等非公共误差的影响。本文给出了一种处理多径误差的方法，设计了相应的Ｋａｌｍａｎ滤波器，利用误差模拟技术对该方法进行了验证，模拟结果表明该方法是有效的。

DGPS is a high-accuracy positioning system,which has agreat potentiality .But its accuracy is affected by the multipath error and othernoncommon errors.This paper p resents an algorithm for multipatherror separating by means of Kalman filtering.Simulation shows that thisalgorithm is effective.
