Absolute airborne gravimetry: a feasibility study

Geophysical Prospecting, 2011
ABSTRACTWe report here the results obtained during a feasibility study that was pursued in order to evaluate the performances of absolute airborne gravimetry. In contrast to relative systems, which use spring‐type gravimeters, each measurement acquired by absolute systems is independent from the others and the instrument is not suffering from problems ...

Wavelets in Airborne Gravimetry

Chinese Journal of Geophysics, 2004
AbstractThree sets of continuous wavelets are constructed for the filtering processing in the airborne gravimetry. The continuous wavelet filters are used to do the low‐passing, first‐order derivative and second‐order derivative filterings at expected space (or time) scales for the airborne gravimetry data.

Airborne and Shipborne Gravimetry at GFZ with Emphasis on the GEOHALO Project

International Association of Geodesy Symposia, 2015
In 2011 the German Research Centre for Geosciences (GFZ) purchased a new mobile gravimeter Chekan-AM. To be prepared for the GEOHALO mission the performance of the new instrument was tested in two shipborne campaigns. The achieved high repeatability of gravity measurements (within 1 mgal) completely met the expectations.

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
