GRAVITATIONAL MODEL OF THE EARTH OF HEIGH RESOLUTION VALIDATION FOR THE REPUBLIC OF CUBA

Abstract

From the year 2012 so far, several modern gravitational model of the Earth of high resolution has been developed. To validate the models gravitational of the Earth of high resolution for the conditions of the Republic of Cuba they were selected: EGM2008 (2012), EIGEN-6C4 (2014), XGM2019e (2019) and SGG-UGM-2 (2020). The validation was made starting from the statistical evaluation of thousand forty-nine (1049) calculated differences between the geometric and gravimetric anomalies. Starting from the analysis of the results of the statistical carried out evaluations were concluded that, the XGM2019e model is that of more accuracy and the one that better adapts to the conditions of the Republic of Cuba. In correspondence, its propose to adopt it like model of reference to continue perfecting the model of the anomalies of the heights for the conditions of the Republic of Cuba.
