Development of Finite Element Models for the Earth's Gravity Field. Phase II: Fine Structure Disturbance Gravity Representations.

Abstract

This report develops locally valid Chebyshev polynomial representations of gravitational disturbance accelerations to use, for example, in inertial guidance calculations. The gravity field can be accurately represented in this fashion, the computational speed is increased by about a factor of twenty in comparison to point mass representations. (Author)
