Imaging the Earth's interior has always been one of the key challenges in geosciences as it is a prerequisite for understanding our planet's internal dynamics and the coupling between its inner and outer envelopes. Gravity measurements at different altitudes (ground, airborne and space-based observations) provide a unique imaging tool, as they supply direct information on mass changes.
Following decades of research, developments, and industrial transfers, quantum technology has reached a high level of maturity, and it is now possible to deliver operational quantum gravimeters that offer various advantages with respect to devices that have been hitherto used.
Aligned with the objective of strengthening the EU's strategic autonomy and competitiveness, the EQUIP-G project, proposed by a consortium of 20 partners from 11 European countries, has been selected to develop and deploy a network of quantum gravimeters in Europe.
This consortium will represent the first step towards establishing the terrestrial segment of the pan-European quantum gravimetry infrastructure, revolving around a shared Instrumental Park. For this purpose, quantum gravimeters and dual quantum gravi-gradiometers will be employed.
