long-range navigational device which uses radio waves
Loran Definition from Business & Finance Dictionaries & Glossaries
BTS Transportation Expressions
An electronic navigational system by which hyperbolic lines of position are determined by measuring the difference in the time of reception of synchronized pulse signals from two fixed transmitters. Loran A operates in the 1750-1950 kHz frequency band. Loran C and D operate in the 100-110 kHz frequency band. (FAA4)
By the Bureau of Transportation Statistics.

Telecommunication Standard Terms
Acronym for long-range radio navigation . A long-range radio navigation position-fixing system consisting of an array of fixed stations that transmit precisely synchronized signals to mobile receivers. Note: A loran receiver measures differences in the times of arrival of the signals from the various stations. A fixed difference in the time of arrival of the signals from any two stations will define a hyperbolic arc on which the receiver must lie. Three or more stations are needed to remove ambiguities in the position of the receiver. Synonyms long-range aid to navigation system, long-range radio aid to navigation system.

Loran Definition from Encyclopedia Dictionaries & Glossaries
English Wikipedia - The Free Encyclopedia
LORAN, short for long range navigation, was a hyperbolic radio navigation system developed in the United States during World War II. It was similar to the UK's Gee system but operated at lower frequencies in order to provide improved range up to with accuracy of tens of miles. It was first used for ship convoys crossing the Atlantic Ocean, and then by long-range patrol aircraft, but found its main use on the ships and aircraft operating in the Pacific theatre.
