摘要

摘要文章介绍了在地心陆地坐标系中通过梯度测量确定地球重力场参数的结果。计算采用了正则化方法，即在正则方程矩阵中加入正则化矩阵乘以正则化参数。通过对各种正则化参数的计算，得到了对谐波系数的度和阶的修正值 200 和 201，并在文章中以图表的形式进行了介绍。根据得到的修正，计算出了表 1 和表 2 中的幂律离散度。

Determination of the Parameters of the Gravitational Field of the Earth by Gradiometric Measurements in the Earth’s Geocentric Coordinate System

The article presents the results of determining the parameters of the Earth’s gravitational field by gradiometric measurements in the geocentric terrestrial coordinate system. The calculations were performed using the regularization method, according to which a regularization matrix multiplied by the regularization parameter is added to the matrix of normal equations. As a result of calculations for various regularization parameters, corrections to harmonic coefficients of degree and order were obtained 200 and 201, presented in the article in the form of graphs. Based on the obtained corrections, the power-law dispersions presented in Tables 1 and 2 were calculated.
