大陆与岛屿之间的高程传递是当前海洋测量急需解决的主要问题之一。本文研究了利用GPS定位

技术，结合我国现有陆地和海洋重力资料以及其它重力场信息，并运用国内外确定大地水准面的严密理论和算法

来确定高精度的局部大地水准面，最终将我国高程基准从大陆传递到南海海域的岛屿上。-Elevation between the mainland and islands, passing the current marine surveying one of the major problems need to be resolved. This paper studies the use of GPS technology, combined with our existing land and marine gravity data, and other gravity field information, and use at home and abroad to determine the geoid rigorous theory and algorithms to determine the accuracy of local geoid, the final height of our country passing reference to the South China Sea from the mainland islands.
