High-precision gravity field mapping plays a critical role in geological survey, resource exploration, and geoid modeling. The traditional ground-based static absolute gravity measurements possess high accuracy, but they are fundamentally constrained by low operational efficiency and inability to survey complex terrains such as river networks, lakes, and mountainous regions. This study tries to address these limitations through the development of an airborne absolute gravity measurement system based on quantum gravimeters. At a flight altitude of 1022 m and a speed of 240 km/h of the airplane, after a filtering process of 3 km, the measured gravity value shows a standard deviation of approximately 8.86 mGal. Furthermore, a comparative analysis with the EGM2008 gravity model shows a residual standard deviation of 8.16 mGal, validating the consistency of the system with established geophysical references. The experimental results confirm the operational feasibility of quantum gravimeters in scenarios of airborne dynamic measurement, demonstrating the viability of this technological framework for high-resolution gravity field mapping.
