Unreferenced date December 2009 Orphan date February 2009 The High Frequency Global CommunicationsSystem HF GCS is a network of single sideband shortwave transmitters of the United States Air Force which is used to communicate with aircraft in flight, ground stations and some United States Navy surface assets. All worldwide receiving and transmitting sites in the HF GCS system are remotely controlled from Andrews AFB . Before 1 October 2002 it was known as the Global High Frequency System GHFS . HF GCS stations tend to operate in the aviation bands clustered around 5, 8 and 11 12 MHz, although other frequencies are in use. The primary HF GCS voice frequencies are 4724.0 kHz, 6739.0 kHz, 8992.0 kHz, 11175.0 kHz, 13200.0 kHz and 15016.0 kHz. In addition to the HF GCS, U.S. aircraft frequently use Military Affiliate Radio System MARS HF stations 13927.0 kHz and Canadian Forces HF stations 11232.0 kHz to relay messages. One common use for the HF GCS is to place telephone calls from the aircraft in flight by means of the Defense Switched Network DSN to an Air Force base to obtain local weather conditions, to arrange for refueling, and to inform the base of the number of passengers and crew. The HF GCS also carries Emergency Action Messages . Although transmissions are often single sideband, the use of the Automatic link establishment ALE transmission mode is more and more common. New South Wales HF GCS complements the use of satellite communications between aircraft and ground stations.
