GPS天线相位中心偏差三维检定研究

Research of check out of three-dimensional variations of the antenna phase center of the GPS receivors

根据GPS接收机天线相位中心的几何关系，利用旋转天线时相对定位的方法，并结合精密水准测量，论证了一种天线相位中心偏差三维检验的方法，实例表明，该方法具有较高的精度和可靠性，适合于在野外对GPS接收机天线相位中心偏差进行实际检定。

In this paper we testified a kind of method to check out the three-dimensional variations of the antenna phase center according to the geometric relations of the antenna phase centers of the GPS receivers, by the method of relative positioning when rotating antennas and related to the precise leveling survey. Through the examples, we concluded that this method had higher precision and reliabilityand was fit for practical testing of FCV in the fields.
