摘要
文中结合GPS接收机天线检测实例,提出了一种新的GPS天线相位中心偏移量的测定与计算方法,并从空间 基线向量的角度对其进行了论证。该法不仅能测定GPS天线相位中心偏移量,还能利用测定结果对空间基线向量 进行改正。经实例测试,按文中方法测得的三台GPS接收机天线相位中心偏差分别为2.9mm、4.3mm和3.7mm。 由测试实例可知:文中的测定与计算方法简便易行,实用性强,是一种行之有效的GPS天线相位中心偏移量检测方 法。
On a basis of the actual example of inspecting the antenna of the GPS receiver, a new method of measuring and calculating the deviation of antenna phase center of the GPS receiver is put forward in the paper and proved from the angle of spatial baseline vector, which could not only determine the deviation of the antenna phase center of the GPS receiver, but also correct the spatial baseline vector with the measured results. In a practice, the deviations of the antenna phase centers of three GPS receivers measured with this method are 2.9mm, 4.3mm and 3.7mm respectively, which demonstrates that the method is simply in operation and useful in actual measurement, and is indeed a kind of effective way to measure the deviation of antenna phase center of the GPS receiver.
