Abstract: A set of coverage prediction diagrams is presented for the 10.2 kHs signal from eachOMEGA transmitter. The diagrams show the -20 dB signal-to-noise ratio contours (in a 100 Hz noise bandwidth) for both local noon and local midnight. Composite diagrams are also presented on which all individual -20 dB contours are plotted for the current transmitter network’ for local noon and for local midnight. Similar diagrams are presented for the planned full OMEGA operational network. A full-wave signal propagation computer program was employed to generate signal strength-profiles along radial paths from each transmitter. Noise values from the CCIR noise map were applied to the profiles. Sensitivity tables showing the shifts that result from small changes in transmitted power or from seasonal variations in the noise power are also included.
