Fugro Airborne Surveys :: Electromagnetic

By: Fugro Airborne Surveys  09-12-2011


Fugro Airborne Surveys provides a complete suite of airborne electromagnetic (AEM) systems, both helicopter-borne (HEM) and installed on fixed-wing aircraft (FTEM).  Fugro Airborne Surveys, and its predecessor companies, has over forty years of experience in developing state-of-the-art AEM systems and conducting successful surveys.  Our goal is to anticipate and provide effective AEM solutions for the exploration / mapping requirements of our clients.

Fugro Airborne Surveys :: Gravity Gradiometry

This advantage is backed by Fugro’s exclusivity on the best AGG technology coupled with our unique value-added processing and interpretation capabilities. FALCON is the world's first airborne gravity gradiometer and is the only operating AGG technology developed specifically for airborne purposes. It measures minute changes in the earth's gravity to high accuracy and high spatial resolution using both helicopter and fixed-wing platforms.


Fugro Airborne Surveys :: HELITEM

The high power of HELITEM, coupled with the low noise at the receiver due to its placement above and not in the centre of the transmitting loop, ensures the greatest depth of exploration possible for any AEM system. Fugro Airborne Surveys offers the HELITEM system, the world’s most powerful commercially available helicopter-borne time-domain EM system, having a transmitter dipole moment of 2.0 million A m2.


Fugro Airborne Surveys :: Airborne Geophysical Surveys

The most important parameters measured are conductivity (which is the inverse of resistivity), magnetic susceptibility, density, and radioactive element concentration. Gamma-ray spectrometric surveys measure the radiation of one or more of the natural radioelements: potassium, uranium, or thorium, or a specific man-made radioelement.


Fugro Airborne Surveys :: Airborne Gamma-Ray Spectrometry

Fugro Airborne Surveys follows the principles outlined in IAEA Technical Report 323 (Airborne Gamma-Ray Spectrometer Surveying), and in AGSO Record 2000/05 for calibration, data acquisition and processing, but uses more advanced techniques for specific aspects. Either unit can be configured with up to 67.2 litres (4096 cubic inches) of main NaI crystal detector, and up to 16.8 litres of upward looking detector volume.


Fugro Airborne Surveys :: Aeromagnetic

The magnetometers can be installed in fixed-wing aircraft or helicopters, in either "stinger" or "towed bird" configurations, and, in addition to measuring total magnetic field, can be used to make vertical, transverse and/or longitudinal gradient measurements by using two or more sensors.
