<!--!introduction!--> In 2019 the French Aerospace Lab (ONERA) carried out an airborne gravity survey to test their quantum absolute gravimeter, GIRAFE, targeting three different locations in France. This was done with the support of the French Laboratory of National Meteorology (LCM-CNAM), the French Hydrographic and Oceanographic Office (SHOM), the French Laboratory of Geoscience Environment (GET) and the National Space Institute at the Technical University of Denmark (DTU Space). On board the aircraft was also a classical strapdown gravimeter provided by DTU Space, to be used as a reference for the GIRAFE observations. Here we will present the results of the survey along with a comparison with both the classical sensor, marine observations and altimetry derived gravity data. The results show that the GIRAFE estimates have improved dramatically since the first airborne test carried out in Iceland 2017, reaching an accuracy of 0.6 to 1.3 mGal. It is also evident that the long-term stability of the ... : The 28th IUGG General Assembly (IUGG2023) (Berlin 2023) ...
