NAVIGATION METHOD OF UNDERWATER OBJECT BY MEANS OF HYDROACOUSTIC NAVIGATION SYSTEM Russian patent published in 2012 - IPC G01S15/08 

FIELD: radio engineering.

SUBSTANCE: navigation method of underwater object is implemented by means of hydroacoustic navigation system containing navigation base of M hydroacoustic transmitters-responders with various response frequencies and hydroacoustic receiver-transmitter arranged on navigation object. Hydroacoustic transmitters-responders are arranged on drifting stations along water surface and bottom stations at sea bottom. Measurement results are processed as per spatial-time observations. During calculation of coordinates there performed is minimisation of error as per distribution of measured coordinates; at that, to calculation device there introduced are local Cartesian coordinates for the considered spatial-time area in which drifting station, bottom responding beacons and underwater object is arranged.

EFFECT: higher reliability during navigation of underwater objects.
