| 摘 要： | Some GPS points were set up and occupied and reoccupied along the traverse route from Zhongshan Station to Dome-A.The result analysis for the GPS data processed by GAMIT/GLOBK package was presented in this paper.It was indicated that the ice along the traverse route flowed with an 8-25 m/a velocity to the northwest in the last three years,which was the direction of the edge of the ice sheet.The maximum horizontal flow velocity is about 100 m/a.Moreove,due to the ice flow,a 0.2-1 m/a sedimentation rate is achieved.finally,a 1-5m/a^2 horizontal acceleration is achieved from the GPS data of the three different stages.

| Abstract: | Some GPS points were set up and occupied and reoccupied along the traverse route from Zhongshan Station to Dome_A.The result analysis for the GPS data processed by GAMIT/GLOBK package was presented in this paper.It was indicated that the ice along the traverse route flowed with an 8_25 m/a velocity to the northwest in the last three years,which was the direction of the edge of the ice sheet.The maximum horizontal flow velocity is about 100 m/a.Moreover,due to the ice flow,a 0.2_1 m/a sedimentation rate is achieved.Finally,a 1_5 m/a 2 horizontal acceleration is achieved from the GPS data of the three different stages. |
