OMEGA was the first truly global radio navigation system for aircraft, operated by the United States in cooperation with six partner nations. OMEGA was originally developed by the United States Navy for military aviation users. It was approved for development in 1968 with only eight transmitters and the ability to achieve a four mile (6 km) accuracy when fixing a position. 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. OMEGA employed hyperbolic radionavigation techniques and the chain operated in the VLF portion of the spectrum between 10 to 14 kHz.
