大地水准面

The methods for the recovery of gravity filed from satellite altimetry are summarized and studied and the geoid and gravity anomaly grided in 2.5′×2.5′ size over china are recovered from multi-satellite altimetry data. Two methods are used to recover gravity.

6总结并研究了由测高数据恢复海洋重力场以及分离海面地形的方法；利用多代卫星测高资料，以测高轨迹海面高剖面梯度采样为基础数据，分别由垂线偏差法和最小二乘配置法反演了2.5′×2.5′中国海域的重力异常和大地水准面差距；然后采用移去-恢复由高斯滤波方法从平均海面高中分离出15′×15′中国海域的动力海面地形。

In this paper, the basic knowledge of GPS, CORS have been introduced briefly, and the theory and methods of refining the local geoid based upon GPS or CORS have been discussed in detail.

本文首先介绍了GPS、CORS的基本知识，详细阐述了基于GPS技术的昆明市大地水准面精化理论和方法，并利用多年基础测绘资料，确定了昆明市1000平方公里范围内数字高程异常等值线。

Today,GPS has been used to built up the new control networks,to verify and improve the existed ones, or to strengthen the laters, and also be used to match the global or local geoids.

用GPS技术在建立新的地面控制网、检核和改善已有地面网，对已有地面控制网进行加密及在拟合区域大地水准面方面都发挥了重大作用。

The results show that within the Philippine Sea and the South China Sea, short wavelength lineations of the geoid undulation are parallel or cross to magnetic lineations and rifting ridges.

结果表明，菲律宾海和南海显示了与磁条带、扩张脊对应或斜交的高频成分大地水准面起伏条带。
