FIELD: water transport; control of moving articles, ship for example at use of lateral displacement of two points.
SUBSTANCE: proposed method includes selection of point of control, determination of lateral displacement from preset trajectory to point of control and taking it into account in shifting the rudder. Use is also made of additional point of control; both points of control are lie in ship's CL: one in the bow and one in the stern. Shifting the rudder is performed depending on combination of lateral displacement of fore and aft points from preset trajectory; displacement of these points is calculated by their coordinates. It is good practice to measure coordinates of fore and aft points by means of satellite navigation system. Coordinates of fore and aft points may be measured at differential corrections.
EFFECT: improved quality of control; enhanced accuracy of keeping the object at preset trajectory.
