Towards absolute airborne gravimetry using quantum sensors

Kurzfassung

for the AeroQGrav consortium 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 our approach for the concept of the quantum sensor including data fusion to recover the gravity signal, aiming for a resolution of 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 13N16514-21.
