Determination of Parameters of the Gravity Field of the Earth by Gradiometric Measurements in an Earth-Fixed Reference Frame
Year: 2024
Type: article
Abstract: The article presents the results of determining the parameters of the Earth’s gravitational field from 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 200 and 201 were obtained, presented in the article in the form of graphs. Based on the corrections obtained, the power-law variances presented in Tables 1 and 2 are calculated.
