Regularizing properties of stabilizing factors are studied to improve the accuracy of the Fourier series summation by spherical functions, used to describe the Earth’s gravitational field. The efficiency of the tested methods is estimated using the nonregularized global gravity field model ITSG-Grace2014s available on the ICGEM website [8].
