METHOD OF CONTROLLING SHIP MOVEMENT ON LATITUDE AND LONGITUDE Russian patent published in 2014 - IPC B63H25/04 

FIELD: physics, navigation.

SUBSTANCE: method of controlling ship movement on a latitude and longitude enables to control movement of a ship on a given path with time-correction of speed. Time-correction enables to find a ship at a given point at a given time. Using the latitude and longitude as navigation information improves accuracy of controlling movement in both space and time. Accurate control using current and latitude and longitude of the ship given in time is realised based on current determination of the course angle in one of four sectors in the range from 0° to 360°. For large angular changes of the given path, automatic switch to standard control of movement on a given course angle and given travelling speed of the ship is provided.

EFFECT: minimising deviation of the ship from a given path, high cost-effectiveness and safety of controlling movement, passage of the ship through narrow waters and control of switch to standard movement of the ship.
