METHOD AND SYSTEM OF SHIP DEVICES ANGULAR ORIENTATION DETERMINING TAKING INTO ACCOUNT OF ITS HULL DEFORMATIONS Russian patent published in 2016 - IPC G01C21/18 

FIELD: ship building.

SUBSTANCE: invention relates to ship orientation systems and can be used in ship angular orientation systems devices taking into account of ship hull static and dynamic deformations, and also aboard ship systems installation errors. For this, system comprises orientation unit, connected to ship system, ship navigation system, coordinates converters, integrating, multiplying and storage devices, as well as low-pass filters. Orientation unit angular position is performed by closed automatic control systems, formed from system components. Orientation angles current values are calculated by combined processing in common horizontal coordinate system of these angles change rates determined by orientation unit, and orientation angles determined by navigation system. Static corrections to roll and pitch angles are calculated, smoothed by filters and stored as corresponding values differences measured by orientation unit and navigation system. Bearing static correction is calculated, smoothed by filter and stored after determination of roll and pitch angles static corrections. Bearing static correction is determined by directions comparing to each other, around which in given moment in time ship deck inclinations take place in orientation unit and navigation system location places.

EFFECT: broader functional capabilities.
