Attention:
Magnetic compensation flight procedures are required after each new installation of the magnetic sensors.
Summary
Magnetic measurements can reveal the strength and direction of the geomagnetic field. One or two Cesium magnetometers are mounted in a combination of nose and/or tail booms. In addition, a Fluxgate Magnetometer for attitude compensation is installed. The sensor system and real-time compensation are controlled by an external unit (AADC II) mounted in a rack. Magnetic base stations with Overhauser magnetometers are used for ground reference of the airborne measurements.
