中文摘要：
本文介绍了GAMIT数据处理软件的主要模块和数据处理流程。以2014年4月份观测的云南红河断裂带两条跨断层剖面十五个测站数据为例,给出了GAMIT解算的基线结果以及质量评价,并采用武汉大学开发的Cosa GPS软件以及同济大学开发的GPS_Net进行了网平差。结果表明,基线处理绝对精度在1cm以内,相对精度优于1.0e-8。通过引入IGS站观测数据可以得到所有测站在ITRF2008下的坐标,其水平精度在5mm以内,垂直精度在8mm以内。
英文摘要：
This paper introduces the main module and data processing of GAMIT software. The GNSS observation data from 15 stations located in 2 cross-fault profiles of Yunnan Honghe fault zone in April2014 are processed by using GAMIT software,then baseline results and quality assessment are obtained.At last,network adjustment is conducted using Cosa GPS software developed by Wuhan University as well as GPS_Net software developed by Tongji University. The results of both software show that the absolute accuracy of baseline is within 1 cm,and the relative accuracy of baseline is better than 1. 0e-8. By including observation data of IGS stations all 15 stations coordinates in the ITRF2008 can be obtained with horizontal accuracy within 5mm and vertical accuracy within 8mm.
