Airborne Geophysics

AGS_MagSince 2007, Geosan has started Fixed Wing Airborne Magnetic and Radiometric survey with a latest industry standard acquisition system and Cessna Caravan 208B aircraft.

What is airborne geophysical survey?

Geophysical survey is the systematic collection of geophysical data for spatial studies. Geophysical surveys may use a great variety of sensing instruments, and data may be collected from above or below the Earth’s surface or from aerial, orbital, or marine platforms.

Geophysical surveys have many applications in Earth science, archaeology, mineral and energy exploration, oceanography, and engineering. Geophysical surveys are used in industry as well as for academic research.

Airborne geophysical surveying is a process of measuring the variation of several key physical or geochemical parameters of the earth.

ABGSThe most important parameters measured are conductivity, magnetic susceptibility, rock density, radioactive element concentration, and reflectance spectra. Any change in the Earth’s near surface that causes a measurable change in these parameters presents a potential application for airborne geophysics.

The systems used to measure these parameters are electromagnetic, gamma-ray spectrometry, magnetic, and gravity.

Airborne geophysics has always been at the forefront of technological developments and innovation. Modern exploration systems can measure minute changes in the geophysical properties of the Earth with high sensitivity instruments and survey platforms.

Exploration projects utilize GPS navigation and timing, laser and radar altimeters, satellite communications and innovative data processing techniques.
Geophysicists interpret the final data using cutting-edge imaging and modeling software.
