摘　　要：在钱塘江及杭州湾两岸地区分辨率较高、精度较好的GPS水准网的基础上,完成了该区域cm级精度的似大地水准面精化工作,实现了钱塘江及杭州湾区域利用GPS技术快速确定平面位置的同时,也测定了高程。针对项目中的拟合模型、核函数选取、平滑因子选取等关键性技术问题进行研究和解决。On the basis of the higher resolution and better precision GPS leveling network on the coast of the Qiantang River and Hangzhou bay,this paper researches quasi geoid refinement with centimeter level in such areas to obtain high precision height anomaly values,and realizes acquirement of three dimensional coordinate.This paper also studies and solves several key technical problems about the project.
