GAMIT/GLOBK%CGCS2000%coordinate conversion
由于CGCS2000坐标系的推广与应用,GAMIT/GLOBK解算坐标也需转换到CGCS2000系,在分析两者关系的基础上,根据IERS提供的框架间转换参数,通过坐标转换的方式进行归化。经过实验分析,结果表明采用这种方式可以得到精度优于2 cm的CGCS2000坐标,能够满足实际工程的需要。
由于CGCS2000坐標繫的推廣與應用,GAMIT/GLOBK解算坐標也需轉換到CGCS2000繫,在分析兩者關繫的基礎上,根據IERS提供的框架間轉換參數,通過坐標轉換的方式進行歸化。經過實驗分析,結果錶明採用這種方式可以得到精度優于2 cm的CGCS2000坐標,能夠滿足實際工程的需要。

With the application and popularization of the CGCS 2000 coordinate system , the GAMIT/GLOBK calculated coordinates al-so need to convert to this system .On the basis of the analysis of their relationship , the naturalization is done by the way of coordinate conversion with the conversion parameters provided by LERS .According to the analysis of the experiments , the result shows that this way can get the precision CGCS 2000 coordinate that is better than 2cm, which can meet the accuracy requirements of the real project .
