Abstract
A muzzle reference system is provided for correcting errors in aiming signals produced by a fire-control system of an artillery gun having a gun muzzle pivotable about a first axis and movable about a second axis extending perpendicularly of the first axis. A laser beam transmitting unit adapted to be mounted on the gun for movement with the barrel about the second axis, directs a laser beam along an optical axis in response to an activating signal. A reflection unit, adapted to be mounted at the distal end of the barrel, reflects a laser beam received from the transmitting unit along the optical axis substantially along a reference optical axis at a predetermined angular position of the barrel about the first axis. A laser beam receiving unit, adapted to be mounted on the gun, receives a laser beam reflected substantially along the reference optical axis and produces signals representative of the deviation of the reflected beam from the perdetermined optical axis. A processing unit connected to the receiving unit and adapted to be connected to the fire-control system converts the deviation representative signals to aiming correction signals and adds the latter to the aiming signal…
