Combination of Aerial Gravimetry and Gradiometry.

Abstract

This report considers the use of a combined accelerometer and gradiometer system for measuring first and second order gradients of the earth's gravitational potential. In this way it is possible to rigorously separate genuine gravitational effects from inertial disturbances, in both first and second order gradients. The theory is developed at length. Accuracy studies comprise the error propagation along a flight profile as well as the error of interpolation between the profiles. By means of least-squares collocation it is investigated how the additional use of second order gradients improves the interpolation of gravity. Numerical estimates are given.
