Definition

Spherical harmonic coefficient model describing Earth's gravitational field, with maximum degree and order of 2190. This paper uses EGM2008 in orbit analysis to calculate the effects of Earth's non-spherical gravitational field on spacecraft trajectories.

Application Value

EGM2008 Earth Gravity Model is a fundamental concept in cislunar mission design, playing an important role in orbital design and tracking planning.
