|
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. aircraft:bt-67:magnetics (6815) |
