Geodetic Accuracies Obtainable from Measurements of First and Second Order Gravitational Gradients.

Abstract

The accuracy of an airborne accelerometer-gradiometer system is studied for geodetic applications. A detailed analysis of interpolation, downward continuation and mean value determination is given using the method of least-squares collocation. The influence of measuring errors is considered and the effects are contribution of accurate satellite altimetry to a combined accelerometer-gradiometer system is taken into account. The results of this study show that a system of this kind can significantly contribute to our knowledge of the anomalous gravity field if second-order gravitational gradients can be measured with an accuracy of a few Eotvos.
