LGO、TBC、GAMIT对地铁短基线解算的对比分析

Comparative Analysis of TGO, TBC, GAMIT Subway Short Baseline Solution

本文采用LGO、TBC、GAMIT三种软件对中短GPS基线数据进行处理,并借用COSA软件进行网平差。研究结果表明,在处理中短GPS基线数据时,LGO、TBC、GAMIT解算结果均能满足工程需要,但LGO和TBC处理基线是更为快捷、实用的选择。

In this paper, three software, TGO, TBC, GAMIT, are used for short baseline GPS data processing and COSA software for network adjustment. The results show that, in dealing with the short baseline GPS data, LGO,TBC, GAMIT solver results can meet the engineering needs, but LGO and TBC treatment baseline is a more efficient and practical choice.
