Methodology for bore sight alignment and correcting ballistic aiming points using an optical (strobe) tracer

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 (T1, T2, T3 . . . ) following firing of the projectile (at time T0);
• 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 T1, T2, T3 . . . ) following firing of the projectile (at time T0) have a time code pulse corresponding to the precise time with respect to time T0, thereby to distinguish the projectile, which was fired at time T0, 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 (T1, T2, T3 . . . ), thereby to correct for errors due to gun jump.
