FIELD: underwater acoustic equipment, underwater acoustic systems of remote control, subsystems of underwater acoustic telecontrol. SUBSTANCE: proposed device includes signal radiation unit that incorporates generator of coded wide-band control signals, power amplifier and projector of underwater acoustic signals connected in series. The latter has hydrophone, amplifier, decoder of coded wide-band control signals, electromagnetic relay connected in series. Above-mentioned components are supplied from high-capacitance and multiply charged independent power supply source. Output of electromagnet which is output of signal reception unit is mechanically coupled to release and reception unit and release are housed in tight case. Release, halyard, signal buoy securing ascent of entire system to surface of sea are coupled mechanically. Signal buoy houses second signal reception unit incorporating hydrophone, amplifier, decoder of coded wide-band control signals electrically connected in series, key switching radio transmitter and flashing beacon on and off, radio transmitter, flashing beacon and timer of same type as components of first signal reception unit, independent power supply source of same type as that of first signal reception unit, units receiving radio signals and determining distance to its source. Insertion of new components gives possibility for reliable high noise immunity and multiple usage of device for disconnection of underwater article and marking its location on surface of sea which is technical result of invention. EFFECT: reliable high noise immunity and marking of location of underwater object on surface of sea. 2 dwg
