This paper outlines the necessity to maintain a worldwide Omega navigation capability, regardless of the other radio navigation methods used, because of effectiveness and the fact that Omega may operate in an environment excluded to the other radio navigation systems. Omega is a hyperbolic worldwide navigation system operating in the 10 to 15 Khz VLF range. The full complement of Omega stations is scheduled to be completed in 1976. Performance of the Omega system has been demonstrated to be better than plus minus one mile accuracy and is expected to improve to better than plus minus 0.75 miles accuracy, with further refinements in propagation modeling and increases in signal strength. Omega is a relatively inexpensive navigation aid in regions not covered by LORAN, VOR, or Decca. Another important feature of Omega is that it is the only worldwide underwater navigation system which provides a bounded error. The Omega frequencies can be received in up to 50 feet of water. In other radio navigation systems, signal attenuation precludes reception at depths where no surface exposure of the receiving antenna in evident.
