摘要
Abstract
On the basis of constraint of to satellite orbit and the coordinates of IGS stations,4 programs are designed to process the data of 1018 GPS week of fiducial stations of Crustal Movement Observation Monitoring Network of China(COMNOC).Three-dimension similarity transformation is used to compare the results of 4 programs.It is shown that the program of loose constraint to satellite orbit and tight constraint to coordinates of IGS stations to some extent gets same result as the program of tight constraints to satellite orbit and coordinates of IGS stations and there exist apparent translation and rotation among the other programs.It is thought that this is related to the high precision of a priori coordinates of fiducial stations.In addition,how to select the reference frame in processing GPS data is discussed.关键词
