AEROQGRAV - ABSOLUTE AERO QUANTUM GRAVIMETRY

Kurzfassung

Airborne gravimetry fills the gap between local measurements and global gravity field recovery with satellite missions. In this context, quantum sensors based on atom interferometry offer a new tool for absolute measurements of gravity with the perspective of superior performance in comparison to conventional methods. This contribution will introduce the AeroQGrav consortium and our approach for the concept of the quantum sensor to recover the gravity signal, aiming for a resolution of 1 µm/s^2 after 5 s of averaging. AeroQGrav is a collaborative research project of iMAR Navigation, Geo++, TU Braunschweig, Leibniz Universität Hannover, Humboldt-Universität zu Berlin, BKG, TU Clausthal, and DLR, funded by the Federal Ministry of Education and Research (BMBF), FKZ 13N16519.
