In 1992, 85 nations agreed to take part in trials of a new navigation system which makes use of surplus military space technology left over from the Cold War. The new system, known as fans or Future Navigation System, will make use of the 24 Russian Glonass satellites and the 24 us gps satellites. Small computers will gradually be fitted to civil aircraft to process the signals from the satellite, allowing aircraft to navigate with pinpoint accuracy anywhere in the world. The signals from at least three satellites will guide the craft to within a few meters of accuracy. fans will be used in conjunction with four Inmarsat satellites to provide worldwide communications between pilots and air-traffic controllers.
