Abstract
Energy ( ) and mission data ( ) for a guided projectile are transferred from a projectile setter ( ) over an inductive interface ( ). The projectile may include energy storage element ( ) to store the energy and a data storage element ( ) to store the mission data. Precision GPS clock circuitry ( ) of the projectile may receive power from a capacitive energy storage ( ) element during projectile loading until a flight battery ( ) is activated. In one embodiment, the capacitive energy storage element ( ) includes at least one super capacitor ( ) and a gun-hardened capacitor ( ). The clock circuitry ( ) may receive power from the gun-hardened capacitor ( ) if the super capacitor ( ) fails during the launching operation. The capacitive energy storage element ( ) may include one-way energy transfer elements ( ) coupled between the super capacitor ( ) and the gun-hardened capacitor ( ). A regulator ( ) may be coupled to an output of the capacitive storage element ( ) to regulate an input voltage to the clock circuitry ( ).
