A-SAT, or Attack SATellites, was the system of ion cannon arrays, laser cannons, and kinetic kill weapons that served as a missile defense shield for the Global Defense Initiative's space stations, orbital weapons platforms, and spy satellites. While the Ion Cannon satellites could be individually given firing commands from commanders with the required uplink facilities, all of GDI's orbiting weapons and surveillance equipment was governed by the A-SAT control center. Without which, the individual uplink facilities would be rendered useless. & File:TW gameicon.png
