    The Survivable Communications Integration System was the replacement missile Early warning system early warning communication system . SCIS was a program replacement awarded in the 1980s. The system was designed and delivered late , with final introduction in the late 1990s. In a Government Accountability Office GAO article published in 1992, E Systems the prime contractor was significantly over budget and significantly delayed. Management and development problems with the SCIS program have contributed to a 65 percent increase in program costs from 142 million to 234 million and a 3 year delay in completion from 1992 to 1995 . After working on SCIS for 4 years, the prime contractor was unable to deliver a system that could process sensor data fast enough to meet United States Air Force Air Force specifications. To help solve the problem, the Air Force is allowing the contractor to replace the computer platform , for the second time at government expense, with a faster, more powerful model. ref http chnm.gmu.edu cipdigitalarchive files 499 GAOAttackWarningSurvivableComms22pp.pdf ref External articles http oai.dtic.mil oai oai?verb getRecord&metadataPrefix html&identifier ADA298099 http chnm.gmu.edu cipdigitalarchive files 499 GAOAttackWarningSurvivableComms22pp.pdf References Reflist Category Warning systems ...   more details

  1. High Frequency Global Communications System

    Unreferenced date December 2009 The High Frequency Global Communications System 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.
