contenttypeSummary

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 Overhauser magnetometer are used for ground reference of the airborne measurements. They produce readings with a 0.01 nT to 0.02 nT standard deviation while sampling once per second.

Info
CS-3 Cesium Magnetometers are mounted in a tail and a nose boom respectively. Additionally, a fluxgate magnetometer is mounted close to the aileron. Electronics are stored in a rack
The GSM-19 magnetometers are used as base stations continously running on the ground during airborne magnetic measurements.
