摘　　要：本文分析了GAMIT与TBC软件数据处理成果的差异,发现不同解算模式下两款软件解算结果平面位置差异在1 cm内,高程差异较大。具体表现为对天线相位中心进行改正,高程差异在5 cm内,不改正天线相位中心,高程差异约7 cm。TBC软件对天线类型敏感,数据处理时是否选择天线类型可能导致高程有约7~16 cm的误差。In this paper,we analyze the data processing result’s difference of GAMIT and TBC software.The results show that under different solution modes the plane position difference of the two software solution results is within 1 cm,but the height difference is large,which is manifested in the correction of the antenna phase center,the elevation difference is within 5 cm,and the antenna phase center is not corrected,and the elevation difference is about 7 cm.The TBC software is sensitive to the antenna type,whether to choose the antenna type when the data is processed may cause the height to have an error of about 7 cm^16 cm.
