摘要 采用东亚地区13个GPS点2002年84天的观测资料,分别利用GAMIT、BERNESE以及GIPSY三种软件进行解算,并对这三种结果进行了比较分析。结果显示:在解算方案一致的情况下,三种软件的坐标结果分别存在着厘米和毫米级的差异。导致毫米级差异的原因是算法本身的有些不同,而导致厘米级的差异则是因为实现统一参考框架方法的差异。 The coordinates of 13 points in the district of the East Asia are calculated by using GAMIT.BERNESE and GIPSY and their results are compared. The conclusion indicates that a difference of cm-level and ram-level exists between their coordinate results. The reasons induced the difference maybe the dissimilarity between the arithmetics and the errors due to unify the reference frames.
