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.
