SHIP GYROPILOT Russian patent published in 2012 - IPC B63H25/04 G05D1/02 

FIELD: transport.

SUBSTANCE: invention relates to navigation equipment. Ship gyropilot includes control unit, feedback sensor, control modes switch. Outputs of steering wheel, rudder control hydraulic unit and electronic cartographic navigation-information system are connected to input of control unit via control modes switch. Receiver-indicator of GPS satellite navigation system is connected to input of electronic cartographic navigation-information system. Control unit output is connected with steering engine input the output of which is connected with control unit input via feedback sensor. To the control unit, unit for determination of permissible vessel lateral deviation from its guided path is additionally connected. Input of this unit is connected to outputs of the mentioned receiver-indicator and electronic cartographic navigation-information system. In the gyropilot, inertial position navigation system, panoramic hydroacoustic system containing echo sounder with two directional characteristics, two side-looking sonars with switchable directional characteristic, parametrical profile recorder are additionally included. Output of panoramic hydroacoustic system is connected with one more input of control unit. The inertial system by its inputs is connected with output of receiver-indicator and output of log, and by its input-output - with one more control unit input.

EFFECT: invention allows for functionality enhancement of gyropilot, while excluding risk of human factor influence on vessel navigation safety; duty captain's mate works more effectively, fuel and engine oil is saved, navigational safety and sailing safety of heavy-tonnage vessels for hazardous cargoes transportation in constraint navigation environment is increased.
