China's first high-resolution helicopter airborne gravity measuring task adopted low-speed and low-altitude on drape flight. Airborne gravity vibration reduction system is faced with the new helicopter flight platform and flight environment, and a lot of problems concerning the damping system should be resolved. Therefore, the authors conducted data collection and testing for the helicopter airborne gravity vibration reduction system, and the test results obtained can provide the reference basis for the future airborne gravity vibration system design, installation and monitoring.
