运用GPS曲面拟合高程精化锦州市区似大地水准面

Quasi-geoid of Jinzhou through GPS Height Fitting Method Based on Curved Surface

利用已完成的锦州市区基础控制成果对锦州市似大地水准面精化进行了研究。介绍了GPS高程的应用理论,大地水准高的计算方法以及利用曲面拟合法计算大地水准面高,并对结果进行了分析,绘制出高程异常等值线图。

The paper studies the quasi-geoid of Jinzhou through its finished basic control result. The paper introduces the application theory of GPS height and hoth the general method and the curved surface fitting method to measure geodetic height. At last,the paper analyzes the result,and the map ot geoid contour is drawn.
