Omega was initially planned in 1968, and was operational in 1971.
There were eight Omega stations Norway (A), Liberia (B), Hawaii (C), LaMoure, North Dakota (D), Réunion (E), Argentina (F), Australia (G) and Japan (H). The station in Australia was originally intended for New Zealand but was moved to Australia after protests from anti-war protestors.
Each Omega station transmitted a very low frequency signal which consisted of a pattern of four tones unique to the station that was repeated every ten seconds. Because of this and radionavigation principles, an accurate fix of the receiver's position could be calculated.
Due to the success of the Global Positioning Systemsatellites such as this NAVSTAR have been launched since 1978. The Global Positioning System usually called GPS (the US military refers to it as NAVSTAR , is a satellite navigation system used for determining one's precise location and providing a highly the use of Omega declined during the 1990s, to a point where the cost of operating Omega could no longer be justified.
