Claim One:
1. A method of programming a trigger time of a projectile, the method comprising: determining a muzzle velocity of a projectile after said projectile exits from an associated gun barrel; determining an flight speed of the projectile a predetermined time after said projectile has been fired; and accounting for the deviation of the projectile's muzzle velocity and flight speed from those determined by an associated ballistic computer and programming the trigger time during the remaining flight time as the projectile is reaching its target, thereby optimizing the effectiveness of the projectile; wherein determining said projectile's muzzle velocity and flight speed comprises emitting a signal from said projectile at relevant predetermined time after said projectile is fired and determining strength of said signal received by an antenna connected to said ballistic computer, and calculating said projectile's speeds from signal strength-distance data stored in said ballistic computer.
