Deployed on the ground in both fixed-site stations and tactical-mobile units, ground theater air control systems (GTACS) play a critical role on the battlefield. While a GTACS enables radio operators to seamlessly relay orders and other information to fighter pilots, it also imposes a set of stringent requirements on its subsystems including high performance, outstanding reliability and exceptional durability. This solution brief introduces how ADLINK’s complete 3U CompactPCI components helped a United States-based agency find an ideal solution for a GTACS able to excel in a fixed base station or a mobile unit traversing some of the toughest terrain on earth.
