摘　　要：作者作为测绘工作者随第24次内陆冰盖队进行了内陆科学考察,获得了一批重要的科学实验数据。本文根据内陆独特的地理位置,结合数据处理的过程,阐述了数据处理中引用国际GPS连续运行站的必要性,讨论了观测时间的长短对GPS定位精度的影响程度,总结出了其相互制约关系。对今后的南极测绘考察提出了良好的建议。As one of the surveyors in inland ice sheet exploration team of the 24th Antarctic expedition,the author carried out the inland scientific research and acquired a number of important scientific experiment data.Based on the unique inland location,combined with the process of data processing,this paper expatiated on the necessity of introducing international GPS continuous operating reference stations for data processing,discussed the influence of the length of observation time on the GPS positioning accuracy,and summarized their mutual constraints relations.It also put forward the suggestions for Antarctic survey and mapping.
