摘要

测量型天线的相位中心标定是在高精度卫星导航接收机中必不可少的研究工作，在辨析天线相位中心的基础上，分析了产生相位中心偏差的原因，重点研究了天线相位中心的暗室测量方法和室外校准方法，实验证明测量型天线相位中心标定校准之后，在高精度测量的应用中，基线解算后得出的测量精度大大提高，为卫星导航系统高精度测量的工程实践提供了方法指导。%During the measurement in satellite navigation positioning,the antenna phase center deviation affects the result of navi-gation positioning,which can not be ignored for high-precision measurement.Hence,it is essential for high-precision satellite navigation receiver verification to detect the phase center deviation of surveying antenna.In this paper,antenna phase center is described and its phase center variation is analyzed. Anechoic chamber measurement method and outdoor field measurement method for antenna phase center are analyzed.It has been demonstrated that measurement precision is dramatically improved by this sort of methods,which can provide guidance for engineering practice in terms of high precision satellite navigation system.
