Airborne Gravimetry with Quantum Technology

In summer 2023 an airborne gravity survey was carried out utilizing the GIRAFE quantum gravimeter from ONERA and the iMAR classical strapdown gravimeter from DTU. The survey consisted of two parts: (1) In Iceland targeting the Vatnajökull ice cap and some active volcanoes, all expected to have some source of mass variation; (2) A regular survey grid around the Nuuk fjord system as input for Geoid computation, along with a strapdown test of the cold-atom sensor, which is currently operated on a stabilized platform.Results from both instruments will be presented and compared with external information. An intercomparison of the two instruments will be presented along with plans for a new cold-atom sensor designed for airborne applications.
