FIELD: measurement equipment.
SUBSTANCE: invention is related to the field of aerial geological mapping. System comprises towing device with flexible bearing frame. Flexible bearing frame arranged at a distance from aircraft, includes section of transmitter with transmitter loop and section of receiver with detector combined with central axis of transmitter section. Flexible bearing frame has light modular structure, which makes it possible to increase and reduce area of transmitter section surface for achievement of certain survey objectives. Loop of transmitter sends pulse in interval "ON". In interval "OFF" sensor device receives response signal from earth. Differential amplifier joined to sensor device provides for high amplification during interval "OFF". Elements of system are connected to computer, on which control computer program is installed for control of system functions.
EFFECT: improved resolving capacity.
