The effect of the terrain on airborne gravity and gradiometry
Journal of Geophysical Research: Solid Earth, 1988With the development of airborne gravimetry and gradiometry, efficient algorithms are needed to compute gravitational effects of the topography. In this paper, such algorithms based on the fast Fourier transform (FFT) are developed and used for studying effects of terrain representation (mass lines or prisms), height data resolution needed, and the ...

Study on Filtering Methods of Airborne Gravity
Applied Mechanics and Materials, 2013There are a great number of high-frequency and low-frequency noises in the airborne gravity data, so the filtering technology is needed to pick up the weak gravity anomaly. Based on the current filtering methods in airborne gravity data processing: butterworth infinite impulse response(IIR) filtering, window function finite impulse response(FIR ...

Airborne Gravity Tests In The Italian Area
EGM 2007 International Workshop, 2007Summary Airborne gravimetry is a valuable method for measuring gravity over large un-surveyed areas. This technology has been widely applied in Canada, Antarctica and Greenland to map the gravity field of these regions. In 2005, two tests in the Italian area have been performed by ENI in co-operation with the Politecnico di Milano and the Danish ...

New concepts for airborne gravity measurement
Aerospace Science and Technology, 2001Abstract A fundamental survey of vehicle mounted gravimeters shows the superposition from the gravity and the kinematical acceleration due to item modification. The particular problems of airborne gravimetry lie in the presence of relatively strong disturbances due to air turbulence.

A geoid solution for airborne gravity data
Studia Geophysica et Geodaetica, 2009Airborne gravity data is usually attached with satellite positioning of data points, which allow for the direct determination of the gravity disturbance at flight level. Assuming a suitable gridding of such data, Hotine’s modified integral formula can be combined with an Earth Gravity Model for the computation of the disturbing potential (T) at flight ...

Arctic Airborne Gravity Measurement Program
1997Gravity data over the Arctic Ocean region are sparse due to the permanent ice-pack which precludes conventional shipboard measurement. Satellite altimetry from ERS-1 is contributing to the coverage at some level of accuracy and resolution, but is also limited by the inclination of the orbit. Although quantities of ice-surface and submarine gravity have

Keynote: Helicopter Airborne Gravity Gradiometry
2nd Conference on Geophysics for Mineral Exploration and Mining, 2018Summary Rotary-wing airborne gravity gradiometry provides both better signal-to-noise and better spatial resolution than is possible with a fixed-wing survey in the same terrain by virtue of the low altitude, low speed and close terrain following capabilities of a helicopter.
