Abstract : The paper briefly discusses gravity gradiometer applications. It outlines the estimation of first order derivatives of the anomalous gravity potential from Bell gravity gradiometer and auxiliary data in the context of a Wiener-Kolmogorov optimization scheme under consideration of computable topographic noise, accomplished on the basis of the Pellinen-Moritz solution of the boundary value problem of physical geodesy. The paper also addresses four different methods of analytical upward continuation of first order derivatives of the anomalous gravity potential under identification of a finite difference method using Laplace's equation as the most economical and efficient one. Keywords: Gravity gradiometer applications; Topographic noise.
