As alternatives to lengthy globally valid series representations of the geopotential, piecewise modeling for the gravity field is investigated. A degree 23 spherical harmonic representation is replaced by 1500 local gravity functions within the spherical shell from 1 to 1.2 earth radii. Worst case acceleration errors enter in the 7th significant digit, computational speed is improved by an order of magnitude. (Author).

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).

Methods are developed and demonstrated for constructing piecewise local models for gravity anomalies. The approach is shown to be computationally more efficient (by a factor of about 20) than competing methods. The report includes software listings and test cases. (Author).
