OMEGA Navigation System Synchronization

Abstract

OMEGA is a long-range (10,000 nm), ground-based, very low frequency (VLF) navigation system which operates in the 10 to 14 kHz navigation band. Eight transmitting stations carefully sited throughout the world broadcast omni-directional, time-multiplexed 10 kW signal on 10.2, 11.05, 11.33, 13.6 kHz plus one frequency unique to each station. The timed transmissions allow easy identification of both station and phase. Phase measurements from three or more stations provide users with latitude and longitude to an accuracy of four nautical miles for 95% of the time. It is estimated that there are about 15,000 worldwide users of OMEGA.
