OMEGA

OMEGA
Lanes and lines of position generated in OMEGA.
An obsolete ground-based, long-range, radio navigational aid, in which aircraft position was derived from the phase measurement or phase comparison of VLF (very low frequency) signals in the 10 to 14 kHz band. Every ten seconds, each of eight stations located around the world radiated a unique pattern on four common frequencies (10.2, 11.05, 11.3, and 13.6 kHz) in time-sharing cycles with a silent 0.2-s interval between each transmission. Besides these common frequencies, each of the stations transmitted on a unique frequency. Any time an aircraft OMEGA receiver received three frequencies, the lines of position were fixed by the OMEGA navigational system computer. A highly automated aid, it provided highly accurate information about the wind velocity, time, distance, and course to the destination or waypoint; ETA (estimated time of arrival); and the present location of the aircraft.
