METHOD OF NAVIGATING UNDERWATER OBJECTS AND SYSTEM FOR ITS IMPLEMENTATION Russian patent published in 2016 - IPC G01S15/04 

FIELD: navigation.

SUBSTANCE: this group of inventions relates to methods and systems for navigation of underwater objects, namely, to methods and systems, when receiving by located on hydroacoustic buoys receivers signals from satellites, finding coordinates of the hydroacoustic buoys by means of computing modules of the hydroacoustic buoys, transmitting data on location and identification data in the form of hydroacoustic signals emitted by the transmitters of the hydroacoustic buoys, receiving the signals by located on an underwater object receiver, finding coordinates of the underwater object by the delay time of receiving the hydroacoustic signals from the hydroacoustic buoys, location of which is known. This solution can be used for simultaneous determination of geographic position of an unlimited number of underwater mobile objects, remote-controlled underwater vehicles, divers, marine animals, etc. in motion. According to the invention encoded are signals from the said hydroacoustic buoys in the form of periodic signals associated to clocks of GPS/GLONASS, all transmitters of the hydroacoustic signals are positioned at the same depth, decoded are the signals from the hydroacoustic buoys with simultaneous separation of straight signals of the hydroacoustic buoys from reflected ones. System implements the said method.

EFFECT: technical result is the increase of accuracy of navigation of underwater objects.
