Abstract: A method for determining correction during steering of a point on an object towed by a towing device, the object point, toward a target position, the object being provided with a bird, including the steps of determining a target position; determining the position of the object point, determining the speed and acceleration of the object point and directions of these and thereby determining an inline direction; determining whether the inline is directed toward the target position and if it deviates from the desired direction, determining a distance vector between the object point and the target position; calculating the object point distance, speed and acceleration components at least in the lateral direction or the vertical direction; and transferring values for the components to a control system for the corresponding bird.
