Mobile Geophysical Technologies collects, processes and interprets magnetic data sets related to the Earth's surface and the soils and rocks beneath. MGT is a high-technology group backed by strong R&D teams in Germany and Switzerland and experienced professionals.
Our services include survey planning, permitting and shipping of equipment worldwide. Typical applications are:

• Mapping geological structure and lithology
• Mapping of old mine sites
• Mapping of industrial contaminants
• Mapping of unexploded ordnances (UXO)
• Mineral exploration
• Engineering projects
• Archeology

As a novelty in geophysics MGT employs an unmanned aircraft system (UAS) that provides a rapid and cost-effective geophysical measuring platform. Our magnetic sensors The UAS is capable of fully autonomous flight, which operates in the way point route plan mode. In this mode the helicopter flies a pre-programmed series of way points (coordinates, heading, altitude, speed).

Results of aero geomagnetic field measurements employing an unmanned helicopter system were obtained from a joint scientific project between MGT and the Geophysical Institute of University of Cologne. This study was funded by the "Deutsche Forschungsgemeinschaft" under contract No TE170/12-1.

In order to provide real-time tracking of orientation or attitude of our sensor system we utilise an INS sensor system, that provide independent orientation from the Earth’s magnetic field as a reference.

ADVANTAGES OF UNMANNED HELICOPTERS

• Enables spatial geophysical surveys on dense measurement grids
• Allows operation at extremely low altitudes above ground (ca 1 m)
• capable of safely operating in hazardous environments such as offshore or high mountains
• Ideal platform for mid-sized surveys (0.1km² to 10km²)
• Quick data collection even in rough or rugged areas
• Enables autonomous flight that reduces field labour and number of field personnel
• Extreme flexible deployment in any region worldwide
• Much faster than ground or vehicle based geophysical measurements
• Ideal for small object detection buried in the soil or inshore waters
