COMPACT AUTONOMOUS SEISMIC-ACOUSTIC STATION Russian patent published in 2017 - IPC G01V1/38 

FIELD: physics.

SUBSTANCE: compact autonomous seismic-acoustic station (CASAS) containing the equipment carrier (AC) mounted on the seabed and popping-up after the ballast recoil, is declared. The equipment carrier AC contains an on-board computing unit (BCU), power supply, a triaxial geophone placed in the sealed spherical container and a hydrophone, a device of setting and taking the AC from the ground, a search tool for the floated AC made in the form of the flashing beacon, of the satellite navigation system "Glonass" of the low-orbit satellite communication system "Gonets", and an active radar reflector, a breaker duplicated by the commands from the urgency device installed outside the sealed container with the tightness sensors, the pressure sensor registering the path consisting of the four-filtration and gain unit providing filtering of the signals from the triaxial geophone and the hydrophone outputs in the frequency band of 5-200 Hz, and the amplification of signals for their application to the input unit of the four-channel analog-to-digital converter (FADC), the output signals from which are served separately on the input channels of the generator (CG), where an array of the separate samples with a length of the sixteen-bit words, supplied from the output of the CG to the respective channels of the information storage (IS), which is a solid-state memory of the four flash cards with a capacity of 2 GB each, is formed from the hydrophone and seismic sensors . The FADC unit consists of four 14-bit ADCs. The device of setting and taking the AC from the ground is made in the form of n pontoons placed in tiers, forming a truncated pyramid and equipped with the cylinders of the compressed gas and the respective inlet and outlet valves. The search tool for the floated AC, made in the form of the flashing beacon, of the satellite navigation system "Glonass" of the low-orbit satellite communication systems "Gonets" and the active radar reflector, are placed in the navigation buoy connected with the CASAS cable-coupling, in which the cable is made in the form of the hydrosensor cable.

EFFECT: provision of the more reliable area studies.
