摘要
高精度定位和定规软件GAMIT/GLOBK,在处理长基线和连续时段的静态定位GPS数据方面有很多优势。本文阐述了GAMIT/GLOBK的GLOBK模块获取全球框架下坐标的基本步骤。然后结合云南省部分CORS数据,阐述获得区域站ITRF坐标的数据处理过程,说明可以通过GAMIT/GLOBK得到区域站的高精度ITRF坐标。最后用MATLAB实现将区域站的ITRF05解算成果转换为高精度CGCS2000坐标。
As a high precision positioning and orbit determination software, GAMIT/GLOBK has many advantages in handling long baseline and continuous-time static positioning GPS data. In this paper, the basic steps of data processing in solving global framework coordinates are described. CORS data of Yunnan Province is processed to demonstrate the data processing of getting ITRF coordinates of regional stations. It is concluded that high-precision ITRF coordinates of the regional stations can be obtained by GAMIT/GLOBK. At last, GCCS2000 coordinates with high-precision are obtained on the basis of the regional station on ITRF05 by MATLAB.
