SkyTEM system

The SkyTEM system is a transient electromagnetic (TEM) method.

The variations in the response of the system provides information about the subsurface geology, from near-surface layers down to 400 m depending on the conductive environment.

The SkyTEM system is carried as an external sling load independent of the helicopter's electrical system.

The transmitter loop is mounted around the perimeter of the lightweight lattice frame, while the receivers of the vertical Z- and the horizontal X-component are rigidly mounted at one end of the elongated hexagonal frame. This construction ensures a well defined geometry at all times and additionally allows for a low, effective terrain clearance of the system.

Magnetometer

The magnetometer can be deployed as a stand-alone airborne survey or integrated with the SkyTEM system.

Magnetometer integrated with SkyTEM

The cesium magnetometer is located on a boom in front of the lattice frame

The magnetic system is synchronized with the TEM system and measures during the TEM off-time.

Stand-alone airborne magnetic survey

Employed as a stand-alone system the cesium magnetometer is towed in a bird beneath a helicopter.

During the survey height, inclination and position is measured along with the total magnetic field.

The aeromagnetic data and survey parameters are accessible for viewing on-time during the flights.

The system is very compact and can even be brought on an aircraft as carry-on luggage.
