Marine/aviation: Omega: Global navigating by VLF fix: This internationally sponsored global VLF system is nearing full operational status

Omega is shaping up as the only system that meets the world's need in the rest of this century for simple, economical, moderately accurate navigation by sea and air. Now nearing full operational status, this VLF system will provide worldwide, all-weather position fixes with root-mean-square accuracy of 1-2 nautical miles. The minimum receiver cost is perhaps the lowest of any navigation system - just a few thousand dollars. Thanks to steady increases in microprocessor applications, a user just enters initial position, and the system can continuously read out positions anywhere on the globe.
