GEOFAST - A fast Gravimetric Estimation Algorithm.

Abstract

A mathematical algorithm called GEOFAST which uses modern frequency domain estimation techniques is developed for estimating gravity quantities such as the undulation of the geoid and the gravity disturbance vector. GEOFAST removes a restriction associated with an earlier algorithm, namely that data tracks be significantly longer than the correlation distances of the gravity quantities being measured. In the new algorithm no restrictions are placed on data track length. (Author)
