摘　　要：文中运用GAMIT/GLOBK软件,解算了南极长城站GPS接收机天线在不同的相位中心和使用不同星历情况下的天顶总延迟,分析了在不同条件下解算结果的差异,探讨了获取高精度的天顶总延迟和实时获取天顶总延迟的具体方法,为今后实现GPS精密定位和实时天气预报提供了依据。The tropospheric zenith total delay over Antarctic Great Wall station are solved by GAMIT / GLOBK software in both cases such as the different ephemeris, the different phase center of GPS receiver antenna. The solving results are analyzed to draw that eccentric phase center of GPS receiver antenna has a greater impact on the solving results and the zenith total delay solved by the forecasting ephemeris and precise ephemeris data are almost same. Therefore, it is a useful significance for high-precision positioning and real-time weather forecast.
