Quantum gravimeters in a nutshell

What is FIQUgS?

Gravimetry aims at unveiling the density structure of the undergrounds by measuring subtle changes of the local gravity acceleration.The first-generation of quantum gravity sensors (QGs) has received a strong interest from many customers, and the market is still growing. But the commercial potential and the positive-impact of the technology are not yet fully exploited because of several limitations such as transportability, robustness, user-friendless or high operation costs. To overcome the barriers that limit the operational utilization of field gravimetry and develop the solutions that will allow us to fully address the exploitable market, we propose to conduct in FIQUgS the development of several innovations, either at the technological level with improved QGs built upon a reliable and efficient supply chain, or in terms of operational methodology.
The development of a next generation QGs product line, and the services associated for the conduction of field surveys, data acquisition and data inversion will allow to considerably develop our capability to address the market of advanced geophysics.

The unique industrial and technological capabilities that will result from FIQUgS will positively contribute to several important societal objectives, especially the European Green Deal:
- the new field QGs will allow for a reduction of the environmental impact associated to mining activities thanks to a reduction of drilling operations, and civil engineering where it will contribute to more efficient and resilient constructions.
- they will contribute to an improved utilization of geothermal energies through the development of non-invasive monitoringcapabilities of the energy reservoir.
- they will be involved in CO2 storage operations and will contribute to the fight against global warming thanks to these advanced monitoring capabilities.
