Reconstructing gravitational field of GRS80 by using simple mass distribution


Abstract
The gravity field of GRS80 was successfully reproduced with high accuracy within 0.07 microGal using three point masses and five ring-shaped masses with the center of mass on the axis of rotation. Gravity from a ring-shaped mass can be calculated by a complete elliptic integral of the first kind and a complete elliptic integral of the second kind.
