SELF-PROPELLED HYDROACOUSTIC BUOY-BEACON AND NAVIGATION EQUIPMENT METHOD OF SEA AREA Russian patent published in 2020 - IPC B63G5/00 B63G6/00 B63G9/00 

FIELD: navigation systems.

SUBSTANCE: group of inventions relates to the field of marine equipment and can be used for navigation equipment of sea areas, provision of safety of navigation and determination of coordinates in sea of surface ships, underwater objects. Self-propelled hydroacoustic buoy-beacon has a current source, control equipment, an antenna and a GLONASS satellite navigation system receiver, underwater communication equipment, hydroacoustic signals reception and reception equipment, receiving amplifier and decoder, beacon electronic equipment, anchor device with anchor, anchor rope and track. In addition, buoy-beacon is equipped with radio transmitter and antenna to provide signals of its location when surfacing on surface, as well as a storage device for recording hydroacoustic signals and noise in the setting area, a computing device and hydrostatic pressure and hydrodynamic pressure sensors. For naval navigation equipment, number of hydroacoustic buoys-beacons required for navigation equipment of preset sea area is calculated, and points of their installation are determined. On the base, the hydroacoustic buoys-beacons are prepared to the installation, checking their serviceability and loading onto the watercraft, they are delivered to the specified sea area and at design points they are discharged into water, after water-shuttle hydroacoustic buoys-beacons are switched to the working position. At the stationary buoys the anchor is separated, the buoy rope is unwound and installed on the ground, leaving the float buoy, as well as the drifting buoy, on the water surface, radio station, satellite navigation system receiver, set of satellite communication and sound underwater communication equipment. Geographic coordinates of each buoy are obtained from the satellite navigation system and, on request of surface or underwater floating crafts, are transmitted over radio or underwater communication.

EFFECT: operational and concealed navigation equipment of the sea area is achieved in order to improve safety of navigation in it, improve the quality of operation and maneuvering of the floating equipment due to their accurate navigation parameters.
