ABSTRACT:
The present invention relates to a method and an apparatus for the reduction of the magnetic identity for such ship parts, primarily ship's guns, the aiming, fire control and possibly firing of which are controlled by a computer. The computer is used to control amplifiers which supply electromagnetic coils built in around the part with the current required for compensation of the magnetic identity of the gun in every specific position. The calculations performed by the computer are based on information on the latitude, course, speed and rolling and pitching position of the ship which it continually fetches from the log of the ship and a gyro reference system as well as on information on the angles of traverse and elevation of the gun which it continuously fetches from angle transducers disposed on the gun.
