南极研究科学委员会 (SCAR) 1995 年至 1998 年间的 GPS 活动提供了宝贵的数据集，用于将南极洲与 ITRF（国际陆地参考系）联系起来，并首次详细了解南极板块的构造行为。数据分析基于七个单独的解决方案，具有四个不同的软件包（Bernese、GAMIT/GLOBK、GIPSY/OASIS II、GEONAP），并提供了研究现有软件噪声的可能性。组合解决方案在 ITRF96 内产生的水平坐标分量的精度为 1 cm，垂直坐标分量的精度为 2 cm。基于三年的重复观测，可以确定南极半岛区域的详细区域形变，并获得整个南极板块旋转矢量的估计。首次总结并介绍了一个由七个工作组组成的非常全面的项目的主要发现。主要重点是该项目的大地测量方面，即使用不同软件包对同一数据集进行分析，以及重复观测的最终结果，即ITRF96中的台站坐标和水平速度。
Scientific Committee on Antarctic Research (SCAR) The GPS campaigns of the between 1995 and 1998 provide a valuable data set which is used to link Antarctica with the ITRF (International Terrestrial Reference Frame), and to gain the first detailed insights into the tectonic behaviour of the Antarctic plate. The data analysis is based on seven individual solutions with four different software packages (Bernese, GAMIT/GLOBK, GIPSY/OASIS II, GEONAP), and provides the possibility to study the existing software noise. The combined solution yields an accuracy of 1 cm for the horizontal and 2 cm for the vertical coordinate components within ITRF96. Based on repeated observations during a total time span of three years, it is possible to determine detailed regional deformations in the area of the Antarctic Peninsula and to obtain an estimate for the rotation vector of the whole Antarctic plate. The main findings of a very comprehensive project of, in total, seven working groups are summarized and presented for the first time. The main emphasis is on the geodetic aspects of the project, i.e. the analysis of the same data set with different software packages, and on the final results from repeated observations, namely station coordinates and horizontal velocities in ITRF96.
