EIGEN-5C incorporates a further extended GRACE and LAGEOS data set, covering almost the entire GRACE period from mid 2002 to end of 2007, but also newly available gravity anomaly data sets for Europe and Australia. However, this new model presents remarkable changes and improvements compared to its precursors. As its precursor EIGEN-GL04C (released in March 2006), this model is inferred from a combination of GRACE and LAGEOS satellite tracking data with surface gravity data, based on the accumulation of normal equations. The global gravity field model EIGEN-5C is complete to degree and order 360 (corresponding to half-wavelength of 55 km) and was jointly elaborated by GFZ Potsdam and CNES/GRGS Toulouse.
In this presentation we report on the latest, recently released EIGEN-model, EIGEN-5C (EIGEN = European Improved Gravity model of the Earth by New techniques) and its associated satellite-only model EIGEN-5S. Global gravity field models play a fundamental role in geodesy and Earth sciences, ranging from practical purposes, like precise orbit determination, to applications in geosciences, like investigations of the density structure of the Earth's interior.

GFZ Potsdam is therefore developing an optimized drilling system for a depth of up to 5000 m, in a joint R + D project with the industrial partners Herrenknecht-Vertical GmbH, a subsidiary of Herrenknecht AG (Schwanau), and H. Research must therefore be done on a flexible and economical drilling system for special applications. The world-wide experience in scientific drilling projects gained by GFZ has shown that there is no commercial drilling system that meets all technical requirements of either geoscientific or geotechnical projects.
