空间大地测量技术对确定地面坐标框架、地形变与地球重力场的贡献和进展--出席2005年国际大地测量协会(IAG) 科学大会札记

国际大地测量协会（IAG）科学大会于2005年8月22~26日在澳大利亚凯尔斯（Cairns）召开。会议名称为“动力行星2005”（Dynamic Planet 2005）。会议就有关完善全球和地区性地面坐标参考框架、卫星重力测量在确定地球重力场时空分辨率、开展航空激光和雷达成像及其干涉技术在地形变和灾害监测,以及对大气的研究、建立和完善全球大地测量观测系统(GGOS)、开展行星大地测量的研究等方面的内容做了广泛的学术交流,内容比较丰富。

CONTRIBUTION AND PROGRESS IN THE DETERMINATION OF TERRESTRIAL COORDINATE FRAME, EARTH DEFORMATION AND EARTH GRAVITY FIELD WITH SPATIAL GEODETIC TECHNOLOGY-Notes on IAG 2005 Scientific Assembly

The Scientific Assembly of International Association of Geodesy(IAG) was held in Cairns Australia,22-26,August 2005.The title of the Assembly is "Dynamic Planet 2005".The following topics presented in the Assembly have a deeply impression on me: the improvement of global and local terrestrial coordinate reference frames,the spatial and time resolution of the earth gravity field variation detected by gravity satellites,earth deformation,disaster and atmosphere monitoring by airborne LIDAR,Radar images and their interferometry techniques,the establishment of Global Geodetic Observation System(GGOS) in IAG,and the development in planetary geodesy study.
