摘要
详细介绍利用GPS数据推算大气水汽含量的过程。根据Saastamoinen和Hopfield两种模型利用实测数据对大气水汽含量进行了推算，并对其结果进行了比较和分析，得到了一些有益的结论。
The calculating procedure of integrated water vapor is introduced elaborately with GPS observations in this paper. According to Saastamoinen and Hopfield models,the integrated water vapor is calculated with real measurements, and comparison and analysis of the results are made, some beneficial conclusions are obtained.
