Webeffort is a new global model of the Earth’s gravitational field: Earth Gravitational Model 1996 (EGM96). In the case of DoD applications, this model replaces the now-outdated original WGS 84 gravitational model developed more than ten years ago. The form of the EGM96 model is a spherical harmonic expansion of the gravitational potential. WebOct 3, 2024 · Why does gravity not qualify as a force? What is space-time curvature?
