| 摘 要： | 基于GPS精密点定位(precise point positioning,PPP)技术,利用IGS的精密星历数据编制软件处理了在Amery冰架获取的连续5d的GPS卫星跟踪观测资料,初步获得了冰架前端观测点处的冰流速度和冰流方向。根据定位解算出的高程系列的周期变化,初步推求出观测点处的海潮周日变化参数。研究成果可为后续的物质平衡计算提供依据。

| Abstract: | The main activities of joint Amery ice shelf expedition between China and Australia are introduced. Five days continuous GPS observation data collected on one site of Amery ice shelf was post-processed with precise point position (PPP) technology based on precise ephemeris of IGS. Dynamic characteristic of the surface ice of Amery can be derived from PPP solution. Preliminary derived velocity of the site and the motion direction is given in the paper. Semidiurnal oceanic tide and diurnal oceanic tide signal of that site can be achieved from the height variation series of PPP solution. The above solution can be used to the consequent mass balance calculation. |
