Airborne Magnetics
The small, lightweight HeliMag system can collect high resolution magnetic data from any Helicopter. It is fully automated which removes the need for additional crew while flying the survey. The Magnetometer itself is a Geometrics G-822A cesium-vapor sensor which is designed for aerial applications.
Geosolutions has developed its own proprietary Magnetometer Counter further increasing sampling rates and quality of the data.
The magnetometer is mounted in a towed bird on a 100ft sling. This removes all magnetic interference from the helicopter (no compensator required) to give the highest quality magnetic data of any airborne system.
Differential GPS and a laser altimeter are also mounted in the bird.
By using a sling from the helicopter, heights and airspeeds considered safe as per the respective helicopter manufacturers Height / Velocity curve can be maintained.
The all up weight of the equipment is approximately 30 kilograms and is flown at 80 knots giving a 1.5 metre sample rate across the ground.
