The high frequency global communications system (HFGCS) is a 24-hour/7-day nonsecure network used by the President and Secretary of Defense, the DOD, and other federal departments, and allied users equipped with HF-ALE radio technology in support of command and control between aircraft/ships and associated ground stations.
The system consists of fifteen communication stations. Fourteen stations are remotely controlled from the Central Network Control Station (CNCS) at Andrews Air Force Base, Maryland. Radio operators at the CNCS use position consoles to control individually each remote HF global station. Figure A-1 depicts system architecture and interstation connectivity. When authorized by the HFGCS ALE network manager, joint ALE users can use the HFGCS ALE network (see appendix B).
