在GPS外业测量中测到的位置，通常是测到GPS接收机天线相位中心的位置。天线的相位中心在实际意义中看不到，是无线电信号接收的瞬时位置，它随着卫星信号输入的强度和角度而改变。本文针对不同的GPS天线，通过实际观测到的数据，利用高精度数据处理软件GAMIT进行处理，分析了不同的GPS天线对解算坐标及解算精度的影响。

In the GPS field,the position of the receiver is usually refer to the GPS receiver antenna phase center . The antenna phase center can not be seen since it is the instantaneous position .It changes with the intensity and angle of satellite signal.This paper studies the effects when different GPS antennas are used to obtain the GPS data .It analyzes the influence of different GPS antennas to coordinates and the accuracy .
