|Advanced Communications Center|
It was distinguished 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.
Prior to the Second Tiberium War, the Ion Cannon Uplink was modularized as a plug-in for the Upgrade Center. By the Third Tiberium War, it was redesigned as a stand-alone structure dedicated to the single purpose of calling down an Ion Cannon strike. It saw its final incarnation during the Ascension Conflict. The facilities from the previous war remained largely the same, but Zone Commanders were also able to designate targets for a network of smaller Ion Cannons without the support of a structure on the battlefield.
