On the impact of airborne gravity data to fused gravity field models

Journal of Geodesy, 2016
In gravity field modeling, fused models that utilize satellite, airborne and terrestrial gravity observations are often employed to deal with erroneous terrestrially derived gravity datasets. These terrestrial datasets may suffer from long-wavelength systematic errors and inhomogeneous data coverage, which are not prevalent in airborne and satellite ...

Broadband Gravity – Combining Vertical Gravity Data from Airborne Gravity and Airborne Gravity Gradient Systems

EAGE 2020 Annual Conference & Exhibition Online, 2020
Summary Gravity data is a powerful tool for oil and gas exploration. Airborne gravity (AG) and airborne gravity gradiometer (AGG) systems each excel at measuring gravity, but at different ends of the typical exploration bandwidth. In order to realize the full benefit of each system type through their combination, a common method of noise estimation is ...

Practical airborne gravity gradiometry

SEG Technical Program Expanded Abstracts 1998, 1998
Established airborne gravity survey methods utilize a single vertical or z-axis gravity meter, such as a LaCoste & Romberg gravimeter, the Global Positioning System, (GPS) or Differential GPS, an inertial and vibration isolation platform, and an exceptionally piloted aircraft to measure the gravity intensity along data lines.
