The envelope of the individual pulses could be used to establish a receiver's internal timing within the 10-second pattern.

However, it was the phase of the received signals within each pulse that was used to determine the transit time from transmitter to receiver.

Using hyperbolic geometry and radionavigation principles, a position fix with an accuracy on the order of 5 to 10 km was realizable over the entire globe at any time of the day.

Omega employed hyperbolic radionavigation techniques and the chain operated in the VLF portion of the spectrum between 10 to 14 kHz.

Near the end of its service life of 26 years, Omega evolved into a system used primarily by the civil community.

By receiving signals from three stations, an Omega receiver could locate a position to within using the principle of phase comparison of signals.
