A navigation system from which hyperbolic lines of position are determined by measuring the difference in times of arrival of pulses from widely spaced, synchronized transmitting stations. Since radio waves travel at the speed of light, a line of position represents a constant range difference from two transmitters. Loran is used by commercial and military ships and aircraft. The name is derived from “long-range navigation.” See also: Hyperbolic navigation system
