Analysis of SCAR92 GPS campaign data was made with the processing software of GAMIT+GLOBK.Because of 'Autcln' functioning in place of 'Cview', preprocessing could be done automatically, which enabled us effective preprocessing. Analysis of 10 days data with 17 Antarctic and southern hemisphere stations yielded the following solutions for the Syowa Station No.23-16 geodetic marker ; that is, with the SI0 precise orbits,X=1766182.964m, Y=1460336.492m, Z=-5932285.883m,while with the GFZ precise orbits,X=1766182.947m, Y=1460336.521m, Z=-5932286.005m, respectively.Standard errors of the daily solution are 4-5cm for most of the stations. Stable pillars are required to ensure within 1cm stability of the solution, instead of the environment-sensitive tripod. For reference, the DORIS-determined coordinates of the same station marker were,X=1766182.526m, Y=1460336.784m, Z=-5932285.380m.

利用GAMIT+GLOBK处理软件对SCAR 92 GPS运动数据进行了预处理，由于Autcln功能代替了Cview功能，预处理可以自动完成，从而有效地进行了预处理。对南极和南半球17个台站的10天数据进行分析后，得出了关于昭和站第23 -16号大地标志的下列解：即SI 0精密轨道X=1766182.964m，Y=1460336.492m，Z=-5932285.883m，而GFZ精密轨道X=1766182.947m，Y=1460336.521m，Z=-5932286.005m，日解的标准误差大多在4-5cm之间。需要稳定的支柱来确保解决方案在1cm范围内的稳定性，而不是对环境敏感的三脚架。作为参考，DORIS确定的同一站标的坐标为，X=1766182.526m，Y=1460336.784m，Z=-5932285.380m。
