GOCE gravity gradients: A new satellite observable
The goal is to perform a comprehensive assessment of the quality and characteristics of the GOCE gravitational gradients as basis for their further use in geodesy, geophysics and oceanography. The project consists of a full analysis of the internal calibration process, a spectral analysis of the gradiometric components individually and of their combination, the determination of the optimal rotation of the gradient components from the gradiometer frame to arbitrary user frames with minimum loss of accuracy and the cross-validation and combination with altimetric data tracks. The project is carried out in close collaboration with IAPG (TU Munich). The figure shows the different work packages and their relations.
