FCC Geodesy

The FCC calls for an evolution, or even a new design, of the geodetic reference systems and geodetic infrastructure already established for the current CERN site, to cope with the demands of a far larger facility. That means not only a significantly improved gravity field model, but also a revision of the geodetic reference systems, frames and datum definitions, the selection of an appropriate cartographic map projection, and a reconsideration of the geodetic facilities and infrastructure at CERN that realise those frames. The project pursues two objectives: determining a high-precision gravity field model for the FCC region, and improving the geodetic reference frames and the geodetic infrastructure.
