Mobile Geophysical Technologies is a near-surface geophysical consulting firm. It specializes in mobile geophysical sensor technologies for cost-effective and rapid collection of geo-located data. It offers vital support to engineering and environmental clients involved in infrastructure projects as well as geophysical exploration services to mining companies.

MGT collects, processes and interprets geophysical data sets related to the Earth's surface and the soils and rocks beneath.
Numerical modelling of electromagnetic problems in borehole geophysics as well as the simulation of the response of nuclear borehole tools is another main pillar of MGT.

MGT is a high-technology group backed by strong R&D teams in Germany and Switzerland and experienced professionals. Our commitment to clients is to provide leading-edge services. Our services include survey planning, permitting and shipping of equipment worldwide.

As a novelty in geophysics MGT employs an unmanned aircraft system (UAS) that provides a rapid and cost-effective geophysical measuring platform. 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 by executing pre-defined mission parameters (coordinates, heading, altitude, speed).

The following video presents an example of an aeromagnetic survey in the autonomous flight mode.

ADVANTAGES OF UNMANNED HELICOPTERS

• Enables spatial geophysical surveys on dense measurement grids
• Allows operation at extremely low altitudes above ground (ca 1 m)
• 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

MGT established a strategic alliance with AEROSCOUT
GmbH, a Swiss high-tech manufacturer in the global UAS
market. The benefits from this alliance are the transfer of
knowledge and expertise, which aims for the synergy to build
and employ innovative, highly integrated geophysical airborne
sensor technology.
