摘要

提出了一种基于电磁建模(EM)技术的GPS载波相位多径信号建模方法。利用商业软件和自主开发的模块对载波相位多径误差参数进行建模和处理。静态多径建模实验表明，该方法可减少约35%的载波相位误差和约25%的三维定位误差。

Estimation of GPS Carrier Phase Multipath Signals Based on Site Environment

This paper presents a method that is based on Electromagnetic Modeling (EM) technique for modelling GPS carrier phase multipath signals. A commercial software plus modules developed in-house are used for modeling and processing carrier phase multipath error parameters. Static multipath modeling experiments show that up to about 35% carrier phase errors and about 25% 3D positioning errors can be reduced.
