Airborne gravimetry; an investigation of filtering [PDF]

open access: yesGeophysics, 1999
Abstract Low-pass filtering in airborne gravimetry data processing plays a fundamental role in determining the spectral content and amplitude of the free-air anomaly. Traditional filters used in airborne gravimetry, the 6X20-s resistor-capacitor (RC) filter and the 300-s Gaussian filter, heavily attenuate the waveband of the gravity ...

IMU and GNSS Postprocessing for High-Resolution Strapdown Airborne Gravimetry

open access: yesEngineering Proceedings, 2023
Strapdown airborne gravimeters based on a navigation-grade inertial measurement unit (IMU) are highly sensitive to perturbations during aircraft flight, especially in the case of flights in draped mode (at a constant altitude above the terrain) or drone ...

Absolute airborne gravimetry with a cold atom sensor [PDF]

open access: yesJournal of Geodesy, 2020
Measuring gravity from an aircraft is essential in geodesy, geophysics and exploration. Today, only relative sensors are available for airborne gravimetry. This is a major drawback because of the calibration and drift estimation procedures which lead to important operational constraints and measurement errors.
