ABSTRACT:
An improved ammunition data transmission system includes alternately applied parallel sources of high frequency of alternating current (AC) voltage and direct current (DC) voltage. The high frequency AC voltage is applied first to provide updated data and to activate the electronic control package for the round in the projectile. the DC voltage then activates the electric primer system for igniting the propellant charge to fire the round. Both the electronics control package and the electric primer system are connected in parallel with the source of AC voltage and, in the preferred embodiment, the parallel connected circuitry contains a capacitor to prevent DC voltage from reaching the electronics control package and an inductor for preventing AC voltage from reaching the electric primer system.
