2000国家大地坐标系框架体系建设及其进展

System Construction and Its Progress of China Geodetic Coordinate System 2000

  • 摘要: 2000国家大地坐标系是我国新一代地心坐标系,启用至今有近7a的时间,推广使用已经全面展开。本文主要评述2000国家大地坐标系坐标框架体系建设中取得的进展,介绍了2000国家大地坐标系框架点的精化情况,并重点描述在框架维持关键技术中建立的2000国家大地坐标系板块运动模型和格网速度场模型,给出了2000国家大地坐标系坐标框架更新的建议。

     

    Abstract: China Geodetic Coordinate System 2000(CGCS2000)is national new geocentric coordinatesystem of China,it has been adopted nearly 7years since July 1,2008,and it is being applied fully indifferent fields.The progress made in the construction CGCS2000framework was reviewed in this pa-per,the refinement of CGCS2000framework was introduced,and especially the plate motion modeland grid velocity field model which modeled in the CGCS2000frame maintaining were focused on de-scription,the update recommendation about CGCS2000frame was given at the end of this paper.
