1985国家高程基准的系统差

Systematic Error of the 1985 National Height Datum

  • 摘要: 基于异常位、高程异常差以及海面地形模型3种方法,分别求出了1985国家高程基准相对于全球大地水准面的垂直偏差,并取得了一致的结果。

     

    Abstract: In this paper, the vertical shift of the origin of the 1985 national height datum with respect to the geoidal surface is calculated based on the methods of the geopotential, the difference of the height anomalies and the sea surface topography model. The results are in good consistent.
