| Abstract: | 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. |
