| (see
e.g. http://www.gfz-potsdam.de/pb1/op/champ/) GOCE will have a
triaxial gradiometer on board. With this gradiometer, the second derivatives of
the Earth potential can be measured in three directions for the first time in
space. An accuracy of a few mE is expected aiming at a geoid accuracy of 1 cm
amd an accuracy of gravity anomalies of 1 mgal with a spacial resolution of 100
km on the Earth's surface. |

GRAND II GOCE-GRAND II (GOCE-GRavitationsfeld-ANalyse Deutschland II) is a network of the following German Institutes for the Analysis of the Earth Gravity Field with financial support by the Geotechnologien Program (http://www.geotechnologien.de/):

| In 2005
the previous project GOCE-GRAND was completed. This project was financed via
the mentioned Geotechnologien-Program as well. Furthermore, this project was
realised in broad cooperation within the German geodetic community; all
GOCE-GRAND I institutes are involved in the new program. The results of
GOCE-GRAND have been published in 2006 in the volume "Observation of the Earth
System from Space", edited by Flury, Rummel, Reigber, Rothacher, Boedecker and
Schreiber at Springer, Berlin Heidelberg New York. Workpackage WP310 Quality Assessment of GOCE Gradients Before entering the final gravity field processing, the quality of the GOCE gradients has to be assessed. For this purpose, a near real-time validation by cross-over (XO) analysis is investigated and will be applied operationally. In addition, regional gravity data will be upward continued to gradients at GOCE altitude, serving as reference gradients for the calibration and validation of the GOCE data. In this context, also the functional model for the external calibration is investigated. Further links concerning GOCE
