摘　　要：本文叙述了作者 1 996年参加“北极追踪”科学考察队进行首次北极测绘科学考察期间 ,使用 GPS全球定位观测系统 ,沿雷索柳特 ( Resolute)—夸那 ( Qaanaaq)—卡波郁科 ( Kap Yok)—尤里科 ( Eureke)—北极点 ( North Pole)—尤里科—雷索柳特的考察路线 ,进行了冰海考察路线导航、寻找北极点、夸那及雷索柳特定点观测。事后采用高精度 GPS数据处理科研软件 GAMIT对采集得到的数据进行了处理、分析 ,得到了观测点的地心及大地坐标和各点到北京的空间基线长。结果表明 ,利用 GPS定位系统在北极地区进行大规模范围内、高精度监测地壳运动和环境动态变化是完全可行的。This article presents the virgin scientific expedition of surveying and mapping while the author was a member of the “Arctic Tracing” expedition team. During it, following the route: Resolute-Qaanaaq-Kapyok-Eureke-North Pole-Eureke-Resolute, GPS( Global Positioning System) was employed to guide the ice ocean expedition route, search out north pole and take fixed point observations at Qaanaaq and Resolute. Whereafter, a specific software for GPS data processing was utilized to process and analyse the data collected during the expedition so that the geodetic coordinates of observed points and the cord length of spatial baselines from each observed point to Beijing were got. The results show that it is feasible in Arctic to utilize GPS to monitor crust movement and dynamic variations of environment with high accuracy within large scale range.
