摘要
GAMIT/GLOBK是目前国际上优秀的GPS定位和定轨软件之一,计算精度高而且开放源代码,应用相当广泛。从2000年起,该软件提供了一些自动处理程序,简化了软件的使用。本文介绍了GAMIT/GLOBK数据自处理程序在不同计算环境下的使用方法和处理步骤。然后通过处理中国境内及周边的IGS站数据,说明了GAMIT/GLOBK数据自处理过程和GAMIT数据处理质量的评价依据。最后,对GLOBK数据处理结果的误差分布进行了简要的分析。
GAMIT/GLOBK is a good kind of GPS positioning and orbit determination software.Due to high calculation precision and open source,it has been widely used.Since 2000 year,it provides some automatic batch running script procedures and simplifies its usage.In this paper,how to use the auto-processing program in different computing environment was described,and the procedure of data auto-processing using GAMIT/GLOBK and how to evaluate the quality of the results were discussed by analyzing the IGS station within and around China.Finally,the error distribution of the results was briefly analyzed.
