论(N-ζ)公式的内涵及推求N的精度

Content and Precision-Determining of Difference Between Geoid and Quasigeoid

    摘要
  • 摘要: 介绍了大地水准面(N)与似大地水准面(ζ)之差公式的推导方法,揭示了其物理内涵,论述了其在精化大地水准面中的重要作用。当似大地水准面精度达到cm级时,大地水准面也将达到同样的精度。

     

    Abstract: The method for formulary derivation between geoid (N) and quasigeoid (ζ) is introduced, and its physical content is announced. If ζ is known precise, then N can be determined precisely.
