Patent ID: 8074555

Claim:
An improved weaponry system comprising: (a) a projectile having a housing, an optical emitter, disposed in the housing, for producing optical signals at pre-determined time intervals following firing of the projectile; (b) a weapon for firing said projectile; (c) a fire control device coupled to said weapon and comprising: i. one or more sensors for measuring angular shift caused by gun jump; ii. one or more sensors for measuring angular position information; and iii. an optical detector for receiving said optical signals; (d) a video processor for processing said optical signals to calculate optical location information comprising lateral drift and vertical drop of the projectile at predetermined times (T 1 , T 2 , T 3 . . . ) following firing of the projectile (at time T 0 ); and (e) a computer having software which identifies a precise aim point for firing subsequent projectiles by determining parameters, said parameters comprising: i. said angular shift; ii. said angular position information; and iii. said optical location information; wherein the optical signals produced at the pre-determined time intervals (at times T 1 , T 2 , T 3 . . . ) following firing of the projectile (at time T 0 ) have a time code pulse corresponding to the precise time with respect to time T 0 , thereby to distinguish the projectile, which was fired at time T 0 , from any other projectiles viewed by the video processor; and wherein said sensors measure angular shift of the optical detector in the horizontal direction and vertical direction at the predetermined time intervals (T 1 , T 2 , T 3 . . . ), thereby to correct for errors due to gun jump.
