Omega Signal Coverage Prediction Diagrams for 10.2 kHz. Volume IV. Bearing Angle Tables.
Abstract
Individual Omega station and composite (Omega Navigation System) 10.2 kHz signal coverage prediction diagrams have been developed for eight times. The diagrams show the global accessibility of 'usable' 10.2 kHz signals at eight fixed diurnal/seasonal times for two usable signal access criteria. Criterion I requires: signal-to-noise ratio (SNR) > or = -20 dB (in a 100 Hz noise bandwidth) and delta phi < or = 20 centicycles (cen), where delta phi is the modal interference-induced phase deviation in the signal phase relative to the reference signal phase. Criterion II differs from Criterion I in that the SNR > or = -30 dB. Volume IV tabulates the bearing angles of great circles to each Omega station. These angles are computed at latitude/longitude grid points having a uniform spacing of four degrees.
