This page shows details on the project. The primary projects are displayed together with a list of sub-projects.

Project description:The project is focused on utilization of gravitation tensor to improve our knowledge about the geometry of the Earth gravity field. In frame of this project we intend to use the measurements of European satellite mission GOCE which launch is scheduled to be in the autumn 2007. Measurements of the second partial derivatives of the gravitation potential are more sensitive to fine anomalous structures of the Earth gravitation field in spite of the smoothing due to altitude of the satellite orbit (approximately 250 km). The project will be in particular focused on following topics: effective processing of satellite gradiometry data, their optimal downward continuation down to the Earth surface, transformation of anomalous gravity tensor to the gravity anomalies or gravity disturbances and optimal combination of satellite and terrestrial data. In the last stage we will use all experiences and results to compile the refined model of quasigeoid and model of deflections of the vertical in Slovakia.
