一种GNSS接收机天线相位中心偏差的原位检测方法
An In-Situ Detection Method for Phase Center Deviation of GNSS Receiver Antenna
摘要
Abstract
To realize the in-situ detection of antenna phase center deviation of GNSS continuous observa-tion station receiver,the equidistant baseline arm method is derived based on the relative method of base-line measurement.According to this new method,a portable equidistant baseline arm device is devel-oped,and field observation data experiments are carried out.The experimental results show that the dif-ference between the in-situ detection results of three different types of GNSS antennas and the arithmetic mean of their conventional detection results over the years is less than the Grubbs critical value.The repeatability of multiple sets of in-situ detection results of the same type of GNSS antenna is less than 0.2 mm.There is no significant difference in the results of 10 groups of contrast detection between these two methods.The equidistant baseline arm method can realize the in-situ detection of antenna phase center deviation without interfering with the continuous observation of GNSS reference stations.关键词
