摘要： A system for controlling the position of a floating vessel consisting of propulsion apparatus capable of moving the vessel, a logic device controlling the propulsion apparatus, and position detecting apparatus for providing output signals related to any algebraic difference(s) between the actual position and heading of the vessel and the required position and heading in relation to a reference datum, arranged so that output signals are fed from the position detecting apparatus to the logic device to cause the logic device to control the propulsion apparatus whereby the position of the vessel is altered in such a manner that the algebraic difference(s) is reduced in magnitude.
