The use of shipborne computer-controlled navigation systems has increased considerably during recent years. The expected advantages depend on the type of vessel; in cargo ships the safety aspect is predominant, whereas in research vessels the accuracy and reliability of position fixing are of primary importance. Generally, computer-controlled navigation systems include a collision avoidance facility operating in conjunction with the radar. This basic equipment is usually extended by a position fixing system, calculating the latitude and longitude from the signals of position fixing transmitters and achieving optimum accuracy by sophisticated weighing techniques (Integrated Navigation). A futher step in automation is the automatic guidance of the ship on preselected tracks. This paper describes such a computer-controlled navigation system, called NAUTOMAT, by which the ship's path is automatically controlled on preselected great circles. The system is packaged in a steering stand and is connected to the gyro-compass, radio navigation receiver and steering gear control. It produces very high control accuracy in areas covered by radio navigation systems. The costs for purchase and maintenance range considerably below those of an integrated navigation system.
