We operate fully oriented three-axial fluxgate magnetometer (Magson) mounted between the two total field (SeaSpy) sensors. These data allow to reconstruct the full vector magnetic anomaly field. Part of the system is an electronic winch and power supply system to regulate the ship current.


The sensors are calibrated in the lab with the specially designed calibration table (right) and additional calibration loops conducted at sea.
