|Advanced Communications Center|
It was externally distinguished from its more basic cousin by built-up transmitter arrays and an enlarged transmitter dish. Not immediately apparent was the enhancement of function; the Advanced Communications Center held the equipment needed to interface with and call fire from the Ion Cannon.
Directing the Ion Cannon required a continuous link between the structure and satellite. If the ground station was disabled by a black out the Ion Cannon ceased repositioning until the uplink was re-established.
The Advanced Communications Center also relayed targeting data to the Ion Cannon from GS-2 beacons placed by front-line troops.
