摘　　要：在高精度GNSS应用发展中,天线相位中心变化(PCV)的改正起到了比较重要的影响。文章综述了三种GNSS接收机天线PCV的精确测量方法,并且根据测量精度,实验复杂度以及成本等多方面因素分析了三种方法的优缺点,最后提出了接收天线PCV测量的发展方向以及可改进之处,有利于我国导航系统天线相位中心变化的测量研究。Antenna phase center variations （PCV） have very important effect on the application of high precision GNSS positio- ning. So calibration of GNSS receiver antenna PCV is worth studying.In this article, three methods of calibration in GNSS re- ceiver antenna PCV are discussed. They are anechoic chamber calibration, relative calibration method, absolute calibration method. Furthermore, the advantages and disadvantages of these three methods are analyzed and compared, including the aspect of accuracy, complexity of the experiment, cost etc. Finally, some improvements are put forward in the field of antenna PCV calibration. These researches are also benefit to the development of navigation in our country, especially in BEIDOU system.
