GPS接收机相位中心偏差检测方法应用

在GPS测量中,观测值都是以接收机天线的相位中心位置为准,而天线的相位中心与其几何中心在理论上应保持一致,可是实际上存一定的偏差。这种偏差的影响,对于高精度定位测量,是不容忽视的,这就要要求对GPS接收机天线相位中心进行检测。本文介绍了检测GPS天线相位中心偏差的旋转天线法以及其数学模型,着重其实际应用。

The method for Examination of Antenna Phase Center Deviation of GPS Receiver

In the surveying process by GPS,the observed data is usually in accordance with the receive antenna phase center,and the antenna phase center should be identical with it's geometric center.But in fact there is a slight deviation,it shouldn't be neglected to the highly accurate orientation survey,so the GPS receive antenna phase center deviation is required to be examined.This text introduces the revolving antenna method that examine the deviation of GPS receive antenna phase center and its mathematics models,paying more attention to the practical application.
