HYDROACOUSTIC POSITIONING AND COMMUNICATION COMPLEX FOR NAVIGATION AND INFORMATION SUPPORT OF UNMANNED UNDERWATER VEHICLES Russian patent published in 2024 - IPC G01S15/06 H04B11/00 

FIELD: electricity; physics.

SUBSTANCE: invention relates namely to communication and radio direction finding systems, and can be used for information and navigation support for unmanned underwater vehicles (UUV) controlled from a support vessel. Essence: a hydroacoustic positioning and communication complex for navigation and information support of unmanned underwater vehicles includes a hydroacoustic positioning and communication system, consisting of an electronic module placed inside the body of an unmanned underwater vehicle, and two different frequency antennas, and a hydroacoustic navigation system based on a long base, consisting of at least three floating hydroacoustic beacons, each of which is equipped with a receiving antenna of a global navigation satellite system and a transmitter, expressed in the form of a hydroacoustic antenna, emitting information about the location of the beacons. The hydroacoustic complex is additionally equipped with at least one automated workstation for the operator of hydroacoustic systems, consisting of a ship operator's console with pre-installed software, a navigation system based on an ultra-short base and a receiving antenna for a global navigation satellite system. The hydroacoustic positioning and communication system is designed to determine the coordinates of each unmanned underwater vehicle in passive mode, i.e. without emitting response signals, and implementing reliable bidirectional information exchange with other devices in various hydrological conditions, using two types of modems: based on orthogonal frequency division modulation and wideband modulation.

EFFECT: increasing the efficiency of interaction between devices of the hydroacoustic positioning and communication complex for navigation and information support of two or more unmanned underwater vehicles.
