New ChallangesNew Challanges
The new challanges of CEGRN focus on Science and Applications Science:
- support the IAG project on Dense Velocity Fields by providing Epoch Sinex files resulting from state-of-the-art processing standards (IGS-EPN guidelines)
- Geokinematical interpretation of the velocity field (TopoEurope project, Wegener) and characterization of areas subject to the largest deformation (Balkans, Dinarids, Vrancea, Eastern Alps)
Applications (direct relation to FP7/FP8 Calls)- INSPIRE: the CEGRN network can serve as geospatial
infrastructure for harmonization of geodetic standards across Europe
- NEREUS (Network of European Regions Using Space Technologies): has one WG on GNSS and one on GMES; powerful lobby in Brussels
- EUPOS: requires stations with high qualification and trained personnel
- Emerging networks: ALBPOS (G.Stangl’s baby!)
