Airborne Magnetometer GT-MAG


GT-MAG on L410
GT-MAG installed on L410 aircraft

GT-MAG can be used as a stand-alone system or can be integrated into EM system. Due to unique measurement technology the quality of GT-MAG data is not affected negatively by the transmitter field of EM system.

Self-oscillating split-beam sensors are used.

At the moment two GT-MAG modifications are available :

 

GT-MAG-2:

provides connection for 2 cesium vapor sensors

GT-MAG GT-MAG back panel

 

GT-MAG-4:

provides connection for 4 cesium vapor sensors

Benefits

SUPER HIGH SAMPLE RATE
GT-MAG magnetometers combine the highest sample rate of magnetic field measurements - 1000 measurements per second - with the sensitivity corresponding to the best cesium-vapour sensors: 0.2 pT/√Hz (the declared sensitivity of CS-3, CS-L sensors produced by Scintrex is 0.6 pT/√Hz). High sample rate provides the solution of the important problems associated with difficult conditions of high-dynamic flights or in the presence of electromagnetic noise
HIGH QUALITY DATA IN THE PRESENCE OF INDUSTRIAL NOISE
Magnetic surveys in industrial areas are complicated due to the influence of electric power lines. When the frequency of measurements is 1000 Hz, correctly applied digital filters suppress this influence.
шум 50 Гц
Suppression of the 50 Hz noise with amplitude of 200 nT
HIGH QUALITY DATA NEAR THE HELICOPTER ROTOR
Rotation of the helicopter rotor leads inevitably to the cyclic influence of its magnetic elements on the magnetic data. The characteristics of the magnetic noise change continually as the angular velocity of the rotor varies. High-frequency measurements provide suppression of this noise by the use of the adaptive digital filter during data processing.
помеха от винта
Suppression of the rotor noise
HIGH QUALITY DATA IN THE PRESENCE OF VIBRATIONS
It does not matter how rigidly the sensor was attached to the aircraft fuselage, mechanical vibrations caused by working engine bring noise at 20-40 Hz frequencies. The amplitude of this noise can exceed significantly a threshold of the sensitivity of the magnetometer. Frequency of 1000 Hz also provides suppression of this influence by the use of the adaptive filtration.
