Abstract

A complexity of solving a task of correction of the spherical harmonical coefficients of the Earth Gravitational Model EGM based on the state gravity anomaly database consists in that a process of the correction of the spherical harmonical coefficients of the Earth Gravitational Model EGM will be iterated by sequential change of the geodetic latitudes of points of grids of the the state gravity anomaly database from small value to biger. This problem complicates computational organization of normalized Legendre functions and increases computational time. This scientific article proposes means of effective computational organization for solving abovementioned task.
