HIGH-PRECISION COORDINATION OF UNDERWATER COMPLEX FOR UNDERWATER NAVIGATION Russian patent published in 2015 - IPC G01S15/00 

FIELD: physics, navigation.

SUBSTANCE: invention relates to underwater navigation and can be used for determination of self-contained unmanned submarine proper coordinates in navigation under ice in high Arctic latitudes. This invention allows ruling out of limiting conditions of said submarine coordinates evaluation because of geometrical (spatial) position of gyro motor and submarine. Application of radio navigation receivers GPS/GLONASS, VHF navigation system at determination of gyro motor position with the help of TV-controlled unmanned submarine system as well as elimination of the use of self-contained unmanned submarine heading and OS direct measurement. Said use brings about incorrect data in high Arctic altitudes. Increase in gyro motor mobility allows decision of the problem of definition of proper coordinates of self-contained unmanned submarine in navigation of under ice.

EFFECT: higher accuracy of locating of self-contained unmanned submarine in high Arctic latitudes.
