资源简介:
The determination of the strain and velocity behaviour of the ice surface near the two German Antarctic Stations on Filchner/Ronne and Ekström ice shelves was performed by the use of various geodetic measuring techniques. The relative positions and heights of control points valid for reference data were deduced from terrestrial observations (horizontal and vertical angle selectro optical distances). After a second sampling of data, these values served as the basis for the deformation analyses. Doppler-Satellite-observations (Navy Navigation Satellite System) made absolute positioning (latitude, longitude, height) of special points possible. These Doppler observations, supported by azimuth measurements (gyro-theodolite and sun observations) provided the datum of control networks (translations and orientation). After the repetition of these observations, the drift rates and azimuths of the control points as wenas the rotanon rates of the surface elements could be given. […]

在菲尔钦/罗恩和埃克斯特罗姆冰架附近的两座德国南极站冰面应变和速度行为的测定,是通过运用多种大地测量技术实现的。基于地面观测(水平与垂直角度选择光测距离)推导出适用于参考数据的控制点相对位置和高度。经过第二次数据采样后,这些值成为变形分析的基础。通过多普勒卫星观测(海军导航卫星系统)实现了特殊点的绝对定位(纬度、经度、高度)。这些多普勒观测,在方位角测量(经纬仪和太阳观测)的支持下,提供了控制网络(平移和定向)的基准。在重复这些观测后,可以给出控制点的漂移速率和方位角,以及表面元素的自转速率。
