GNSS接收机天线相位中心改正对高精度定位影响

内容简介：阐述了GNSS接收机天线相位中心偏差（PCO）的产生原理及其改正模型，同时重点介绍了现阶段我国天线相位中心测定的基本原理及方法，并分析其优缺点，用算例分析了接收机天线相位中心改正对定位结果的影响，针对 GNSS接收机天线的使用以及我国接收机天线相位中心的检测提出了一些思路和建议。

Abstract：This paper first describes the principle of GNSS receiver antenna phase center offset and variation and correction models,then introduces and compares the advantages of bas-ic principles and methods about antenna phase center calibration in china.Finally,a practical example was given to research the influence GNSS antenna phase center corrections on precise positioning,some suggestions are given about the GNSS receiver antenna using and calibration in china.
