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 signals. Monitoring means monitors the position of the barrel about the first axis and applies the activating signal to the transmitting unit when the barrel is at its predetermined position.

A muzzle reference system for correcting errors in aiming signals produced by a fire-control system of an artillery gun having a gun barrel pivotable about a first axis and movable about a second axis extending perpendicularly of said first axis, said muzzle reference system comprising: laser beam transmitting means adapted to be mounted on a turret of said gun for movement with said barrel about said second axis and directing a focalized laser beam along a predetermined optical axis in response to an activating signal; mirror means adapted to be mounted at the muzzle end of said barrel for reflecting said laser beam received from said transmitting means along said predetermined optical axis substantially along a reference optical axis at a predetermined angular position of said barrel about said first axis; laser beam receiving means adapted to be mounted on said turret of said gun for receiving a laser beam reflected substantially along said reference optical axis and producing deviation representantive signals representative of the deviation of said reflected beam from said reference optical axis; means connected to said receiving means and adapted to be connected to said fire-control system for converting said deviation representative signals to aiming correction signals and for adding the latter to said aiming signals; and means for monitoring the position of said barrel about said first axis and applying said activating signal to said transmitting means when said barrel is at said predetermined angular position.
