随着高速铁路在我国的大规模建设，各种等级GPS铁路控制网的布设也陆续展开，用于解算GPS基线的软件，除了各种随机软件如TGO、LGO等外，GAMIT也是一款解算GPS基线的可靠工具，利用GAMIT 可以有效消除长基线观测中电离层的影响，且可以加入潮汐改正。本文介绍了GAM IT 软件在多天多时段工程控制网中的解算流程，以及相应的C SHELL批处理程序，分析了不同星历对基线解算结果的影响，验证了超快速星历与快速星历同样可以获得高精度及高可靠性的解算结果。

With the construction of high railway in China ,GPS control network of different levels has already set up ,except some supporting software such as TGO ,LGO ,GAMIT is also a reliable tool in processing GPS baseline .With the help of GAMIT the Ionosphere effect in long baseline can be highly decreased ,also tide effect can be removed .In this paper ,the pro-cedure using GAMIT in processing GPS network of multi-day and multi-session has introduced by corresponding C SHELL bat program ,and different ephemeris affect on baseline result has analyzed ,a conclusion is draw that Ultra-rapid ephemeris and quick ephemeris worked well in high-precision GPS survey .
