| 摘 要： | 运用GAMIT／GLOBK软件，对南极长城站与周边的各IGS跟踪站的GPS观测数据进行组网解算。在解算各站上空总天顶延迟的过程中，利用不同的星历进行解算，并对其解算结果进行了分析和探讨得出：实时预报。星历与精密星历在解算结果上差别不大，最小差值是0mm，最大差值仅为0．5mm。所以在计算各GPS站上空大气水汽含量时，可直接采用实时预报星历，对今后实时探测水汽及实时天气预报具有一定的实用意义。 |
| 关 键 词： | GAMIT/GLOBK GPS数据 预报星历 精密星历 天顶延迟 |

| Abstract: | The tropospheric zenith delays of Grw1 station in antarctic grouped with Peripheral IGS stations were respectively solved by GAMIT/GLOBK software using GPS observational data according to IGS final ephemeris and broadcasting ephemeris.The results show that the zenith delays of different stations solved by the two kinds of ephemeris data at the same time are almost same.The differential minmum was 0 mm and the differential maximum was 0.5 mm.Therefore,broadcasting ephemeris in this software can be used to solve the zenith delays which are premise of caculating the precipitable water vapor contents on the GPS stations.It is a useful significance for real-time water vapor contents detection and weather forecast. |
| Keywords: | GAMIT/GLOBK GPS data broadcasting ephemeris precise ephemeris zenith delays |
