| 摘 要： | GPS气象学在南极的应用中,南极长城站上空对流层天顶总延迟的解算精度直接影响该站上空的大气水汽含量的估算精度。本文运用麻省理工学院研制的高精度解算软件GAM IT/GLOBK,对引入不同数目的IGS跟踪站与南极长城站的GPS数据分别进行了组网解算,得出了该站上空的天顶总延迟,并解算了该站上空的可降水分,将其与实际降水进行了对比分析,得出了与南极长城站组网解算的最佳IGS跟踪站站数为3个。

| Abstract: | The precision of the total zenith delay in troposphere over Great Wall station in Antarctic directly affects the estimating precision of the water vapor contents in the Antarctica application of GPS meteorology.In this paper,the total zenith delay on GPS observational station was solved respectively by GPS data of Great Wall station grouped with IGS stations of different number using high-precision software-GAMIT/GLOBK developed by the Massachusetts Institute of Technology.Moreover,the precipitable water va... |
