摘要
本课题研究目的主要是利用高精度数据处理软件GAMIT对中国IGS跟踪站坐标进行解算,得出高精度坐标并进行结果分析。利用此软件对北京、上海、武汉、昆明四个跟踪站1年每天的数据进行处理可使其精度达到mm级。利用坐标解算结果用图示将各站X、Y、Z变化情况显示出来,得出其周期变化规律,并将解算结果与IGS网站提供的坐标及精度进行比较。
The main purpose of this research is to use the high-precision data processing software GAMIT to calculate the coordinates of China IGS tracking station,obtain high-precision coordinate and make conduct analysis. This issue is the processing of a year data in four tracking station of Beijing,Shanghai,Wuhan and Kunming and achieving the accuracy of millimeter aided by the software. The changes of the station X,Y,Z are showed up in the results to obtain its changing patterns. And it can make comparison between the calculated results and the coordinates of IGS website.
