OMEGA PROPAGATION CHARACTERISTICS IN THE ARCTIC, TEMPERATE AND TROPICAL REGIONS.
Omega is a very-low-frequency, long-range, hyperbolic radio navigation system under final phases of development. Studies are now being made to determine range capabilities and system stability of the Omega system under actual operating conditions. During October through December 1961, NRL made fligh...
