CONTROLLED MOBILE HYDROACOUSTIC BUOY-BEACON Russian patent published in 2022 - IPC B63G5/00 B63G6/00 B63G9/00 

FIELD: marine technology.

SUBSTANCE: invention relates to the field of marine technology and is intended for navigation equipment of sea areas using underwater vehicles. A controlled mobile sonar buoy-beacon is an autonomous unmanned underwater vehicle equipped with an onboard inertial navigation control system, a power plant with an energy source and an engine, a propeller, steering gear drives and an external tail with rudders, hydrostatic and hydrodynamic pressure sensors. In a separate compartment of the underwater vehicle there is a hydroacoustic beacon buoy with a transceiver radio antenna of a satellite navigation system and equipment for receiving and transmitting hydroacoustic signals, a current source and control equipment with a computing device, a device for recognizing "friend or foe" request signals, a decoder and an encoder. An autonomous unmanned underwater vehicle has one or more ballast compartments with devices for filling them with water and drainage, an acoustic profiler, a memory device, at least one hydrophone, equipment for monitoring the operability of onboard equipment, a radio transceiver with a current source and a communication float with a transceiver antenna located in it, which is connected to the onboard inertial navigation control system by a cable wound on a reel having a drive and a control device.

EFFECT: provision of necessary navigational information for its underwater objects in a given sea area.
