摘　　要：利用国际高精度数据处理软件GAMIT(V10.4)遥感IGS跟踪站武汉站上空的大气水汽含量,总结出GAMIT软件解算水汽含量时的一些常用经验和注意事项;分析了对流层参数个数、卫星精密星历以及卫星截止高度角的变化对大气水汽含量遥感结果的影响,并得出结论。Based on the international high precision data processing software GAMIT （V10. 4）, zenith water vapor content value in IGS tracking station Wuhan was remote sensed. Some common experience and matters to pay attention to were summed up when use GAMIT software to calculate precipitable water vapor. Troposphere parameters number, satellite precise ephemeris and satellite elevation cut-off angle were selected as influencing factors. The change of these factors which affecting the remote sensing result were analyzed. Some beneficial conclusions are obtained.
