Abstract: Energy (110) and mission data (108) for a guided projectile are transferred from a projectile setter (102) over an inductive interface (118). The projectile may include energy storage element (114) to store the energy and a data storage element (112) to store the mission data. Precision GPS clock circuitry (316) of the projectile may receive power from a capacitive energy storage (304) element during projectile loading until a flight battery (320) is activated. In one embodiment, the capacitive energy storage element (304) includes at least one super capacitor (322) and a gun-hardened capacitor (324). The clock circuitry (316) may receive power from the gun-hardened capacitor (324) if the super capacitor (322) fails during the launching operation. The capacitive energy storage element (304) may include one-way energy transfer elements (326) coupled between the super capacitor (322) and the gun-hardened capacitor (324).
