摘　　要：简要阐述了应用GAMIT软件进行数据准备和数据处理的方法,在数据处理部分采用了批处理和分步处理两种方法,并结合国际地球力学服务组织(IGS)跟踪站部分站点所构成的控制网数据进行基线解算和精度分析。结果表明:GAMIT软件解算中长基线的相对精度能达到10-9量级,完全满足各级精度要求。GAMIT is a GPS data processing software which was developed by Massachu- setts Institute of Technology （MIT） and Scripps Institution of Oceanography （SIO）, it＇s a general-purpose GPS data processing software internationlly. The way of data processing is distributed and batching with the GAMIT software, combined with control network data which is consist of part of IGS sites, and so is baseline processing and precision analysis. And the finding is that by using the software GAMIT, the relative accuracy of resolving the middle-long baseline can reach 10-9 , which can completely meets the various levels of preci- sion requirements.
