|
Magnetic measurements provide can reveal the strength and direction of the geomagnetic field. Therefore, 2 Cesium Magnetometers One or two Cesium magnetometers are mounted in a Nose and a Tail Boom to the aircraftcombination of nose and/or tail booms. In addition, a Fluxgate Magnetometer for attitude compensation is installed. The sensor system is 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. Sensor-Info: aircraft:bt-67:magnetics, 6815 |
