The novel automatic control system or automatic pilot controls the course of a ship by means of 1. A GYROSCOPIC INDICATOR FOR INDICATING THE COURSE OR TRUE HEADING OF THE SHIP, 2. A REFERENCE VALUE TRANSMITTER ADJUSTABLE IN ACCORDANCE WITH THE DESIRED COURSE ANGLE OF THE SHIP, 3. SUMMING MEANS FOR DETECTING ANY POSITIONAL DISAGREEMENT OF SAID INDICATOR WITH SAID REFERENCE VALUE TRANSMITTER, SUCH DISAGREEMENT REPRESENTING THE COURSE ERROR AND 4. MEANS CAUSING THE COURSE ERROR TO CONTROL A MOTOR-OPERABLE RUDDER ACTUATOR WHICH SO ACTUATES THE RUDDER OF THE SHIP AS TO REDUCE THE COURSE ERROR TO A MINIMUM. For the purpose of steering the ship along a curved track, as on a winding river, means are provided for driving the reference value transmitter to change the desired course set up therein in the clockwise sense or in the anti-clockwise sense at an adjustable rate. The drive may be effected by a stepping motor actuated by electrical impulses of adjustable frequency.
