摘要
本文将计算重力大地水准面的频域方法推广至空域,提出了一种新的用重力数据和重力模型位系数联合确定大地水准面的方法。利用重力异常的逐级余差实施积分,使得通常的Stokes积分方法具有明确的频域分析含义,可按精度要求确定出使用重力异常余差的块形大小及积分半径ψ_0。

The frequency domain usually used for computing gravimetric geoid is extended to space domain. As a result of this, a new method for determining gravimetric geoid by combining gravity data and geopotential coefficients is proposed using degree-by-degree residuals of gravity anomalies in integral operation as proposed by this method, the usual stoked integral operation will have definite meaning of frequency domain analysis. The block size of applying residuals of gravity anomalies and integral radius are determined according to the requirement on accuracy.
