如何判断gamit基线解算结果可靠

已有 4458 次阅读 2017-12-25 11:37 |个人分类:GAMIT/GLOBK|系统分类:科研笔记

There are three criteria for determining if a solution is acceptable:
1) The uncertainties in the baseline components must have the same magnitude of the a priori constraints applied to station coordinates and orbital parameters
2) A good solution produces a “normalized rms” (nrms) of about 0.25. Anything larger then 0.5 indicates that there are problems (e.g., cycle slips that have not been removed, bad coordinates of the fixed stations, …)
3) The fractional part of the solution (Fract) must be smaller than 10.
