Abstract
Kits or sub-systems that include sensors to measure a projectile's condition at muzzle exit. The kits or sub-systems are coupled to ballistic calculators or fire control systems that calculate aiming and programming solutions to improve shot placement, reduced dispersion and improve terminal performance. Where airburst munitions are used, the projectile is programmed when reaching a programming station beyond the barrel and the projectile is programmed with a solution that adjusts the burst location based on the measured muzzle velocity. Sub-systems, processes and sub-routines optimize “post-shot” programming using certain non-linear methods that are incorporated into fire control systems and ballistic calculators. These non-linear sub-routines are useful in establishing the optimum terminal effect of such airburst projectiles. The sub-systems are used separately or are incorporated into the weapons, to reduce dispersion and improve the terminal effects of the projectiles.
