NAVAL AUTONOMOUS GROUND SEISMIC STATION Russian patent published in 2006 - IPC G01V1/38 

FIELD: geophysics, possible use for controlling seismic processes of sea.

SUBSTANCE: naval autonomous ground seismic station has deepwater self-surfacing geophysical equipment carrier and onboard computing module, mounted onboard the ship. Geophysical equipment carrier includes, positioned in hermetic spherical container, consisting of two semi-spheres, between which compacting rubber ring is positioned: registration block, orientation determining block, made in form of indicators of inclination and azimuth, synchronization block, made in form of timer, synchronized with chronometer, hydro-acoustic transmitter-receiver block, device for controlling release, connected to timer and onboard computing module, power block; mounted outside the hermetic container - hydro-acoustic indicator in form of hydrophone, hydro-acoustic antenna, device for planting and lifting geophysical equipment carrier from bottom soil, made in form of ballast anchor and held by means of release, made in form of electro-chemical release, means for finding surfaced geophysical equipment carrier, made in form of flashing beacon. Registration block includes three-component seismic-receiving module and device for accumulating measuring information. hydro-acoustic antenna through hermetic socket is connected to inputs of hydro-acoustic transmitter-receiver block and device for controlling aforementioned release. Ballast anchor is made with semi-spherical recess for placing container held by means of release. Onboard computing module contains block for taking digital information from measuring information accumulating device, controlling block, block for hydro-acoustic communication with carrier of geophysical equipment, time synchronization device, display device. Ballast anchor is made bucket-shaped of reinforced frame filled with concrete, in semi-spherical recess of which float is positioned provided with halyard. One of inclination-azimuth indicators is mounted on the body of geophysical equipment. Additionally inserted is block of geo-background filters.

EFFECT: expanded functional capabilities of device.
