The Leading Edge, 1982
The recent achievement of useful airborne gravity surveying warrants a re-examination of our current strategy of geophysical exploration for petroleum and natural gas. In the early stage of geophysical exploration, gravity and magnetics were in the vanguard.

Symposium on the Application of Geophysics to Engineering and Environmental Problems 2010, 2010
The gravity tensor measures changes in the three dimensional gravity field along the three axes of motion, giving a nine component array of differentials. Because of symmetry and the Laplacian character of gravity, only five of the components are independent. Gravity has been used for resource exploration since the early 20 th century.

The Greenland Airborne Gravity Project — Comparison of Airborne and Terrestrial Gravity Data
1993This paper describes preliminary results of comparisons of airborne gravity data to ground data for the Greenland Aerogeophysical Project. Upward continuation of ground truth data have been carried out by a spherical FFT approach using terrain models to avoid aliasing. Results indicate accuracies in the range of 6–11 mgal.

Tests of an airborne gravity meter
Geophysics, 1960Abstract Gravity measurements have been made in an airplane and a contour map using 20-mg. interval constructed for 12,000-ft. elevation. The LaCoste and Romberg instrument used is similar to that recently tested on a surface ship.

The Falcon Airborne Gravity Gradiometer for Engineering Applications
Symposium on the Application of Geophysics to Engineering and Environmental Problems 2010, 2010While airborne gravity has been available for decades, only with the advent of airborne gravity gradiometry (AGG), and specifically the FALCON AGG installed in a helicopter, has airborne gravity measurement reached a sensitivity and spatial resolution that can be effective for a wide range of engineering applications. Survey examples and gravity models

Gravity field approximation using airborne gravity gradiometer data
Journal of Geophysical Research: Solid Earth, 1992A set of airborne Gravity Gradiometer Survey System (GGSS) data was used in combination with the OSU89B geopotential model to predict gravity anomalies and deflections of the vertical. The gradiometer data were collected during an airborne survey of the GGSS in the Texas/Oklahoma area.

Airborne Gravity Field Determination
2010Airborne measurement of gravity has long been a goal for geodesy and geophysics, both to serve geodetic needs (such as geoid determination) and in order to provide efficient and economic mapping of gravity anomalies for geophysical exploration. Although airborne gravimetry has been attempted since the 1960s (LaCoste 1967), it is only in the 1990s, with

An historical review of airborne gravity
The Leading Edge, 1998Measuring the earth’s gravitational field may not have occurred to our prehistoric ancestors when they dropped rocks on their toes, but it has certainly intrigued generations of scientists in subsequent centuries. Successful construction of instruments to measure this effect has always relied on trial and error, and the broken toes of previous efforts.

Svalbard Airborne Gravity Project 1998
61st EAGE Conference and Exhibition, 1999In July 1998 an airborne gravity survey was carried out in the Svalbard region as a joint effort of Norwegian and Danish organisations. The primary purpose was to improve the gravity field description of the archipe lago. A secondary goal and the topic of this paper, was to test the usefulness of the airbome gravity system in exploration geophysics ...

Advances in airborne gravity gradiometry at Fugro Airborne Surveys
EGM 2010 International Workshop, 2010In the last five years, considerable progress has been made in airborne gravity gradiometry with Fugro’s proprietary FALCON technology. Noise levels have nearly halved and the routine incorporation of regional gravity data has led to very wide bandwidth gravity data.
