In August 2021, the National University of Defense Technology carried out a gravity measurement test with the ch-4b fixed wing large UAV as the carrier, integrating the Beidou satellite navigation system (BDS) and the self-developed SGA-WZ04 gravimeter. The test carried out several sorties of offshore survey line flights and collected a large amount of gravity data, including repeated survey line data. In this paper, the self-developed gravity data extraction algorithm based on Beidou difference is used to process the test results, and the internal coincidence accuracy of its repeated measurement line is 0.65 mGal/3 km, which is equivalent to the current UAV airborne gravity measurement method based on GPS (0.66 mGal/3 km). The test verifies the feasibility of the application of domestic satellite navigation system in gravity measurement, and the stability of the UAV airborne gravity measurement platform in the actual operation under a large amount of tasks, which makes a strong exploration for further realizing the localization and unmanned of the airborne gravity measurement system.
