Abstract
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.
