OPLE: Omega Position Location Equipment

Omega was a very long-range Very Low Frequency (VLF) navigation system and the first navigation system providing true global coverage. The system worked by generating hyperbolic lines of position (LOP) by means of phase difference measurements of VLF time-shared transmissions emitted by widely spaced antennae.

It was a hyperbolic navigation system, enabling ships and aircraft to determine their position by receiving very low frequency (VLF) radio signals in the range
