摘要
重点介绍了高精度确定大型天线几何旋转中心的观测方案和计算方法。结合具体实例,在ITRF2000框架下,论述了控制网布设、观测方案确定、数学模型的建立、数据处理的过程,结果与已知外部参考结果进行了比较,坐标分量上达到毫米级外附精度,验证了观测、计算方案的可行性和准确性。
This paper specified the observation and computation method for determining the big antenna＇s geometric rotation center. Under the ITRF2000, compared with the reference result the center＇s coordinates reached millimeter level, which also testified that the method introduced in this paper was feasible and accurate.
