Airborne Absolute Gravimetry With a Quantum Sensor, Comparison With Classical Technologies
Journal of Geophysical Research: Solid Earth, 2023 We report an airborne gravity survey with an absolute gravimeter based on atom interferometry and two relative gravimeters: a classical LaCoste&Romberg (L&R) and a novel iMAR strap-down Inertial Measurement Unit (IMU). We estimated measurement errors for
