A system of electronic navigation in which a vessel or aircraft determines its latitude and longitude by measuring the time differences between low frequency radio transmissions from two stationary transmitters (slaves) and a stationary master transmitter. Contrary to the name, Loran is a medium range system, usually effective for no more than a few hundred miles from shore. The first commercial system was called Loran A; the latest (and final) development is Loran C.
acronym for Lo ng Range adio avigation; a navigation system in use during the SEA war; not on Skyraiders
A satellite positioning system used for navigation in bad weather. Boats equipped with a Loran are usually safer than ones without it.
Hyperbolic grid navigation system
A positioning systems using broadcast radio waves from a known positions to determine your location. Is being replaced by GPS
a radio positioning system that allows navigators to make position fixes by the reception of synchronized low-frequency radio transmissions. The word loran is an acronym for long-range navigation.
Loran, which stands for LOng RAnge Navigation, is a grid of radio waves in many areas of the globe that allows accurate position plotting. Loran transmitting stations around the globe continually transmit 100 kHz radio signals. Special shipboard Loran receivers interpret these signals and provide readings that correspond to a grid overprinted on nautical charts. By comparing signals from two different stations, the mariner uses the grid to determine the position of the vessel.
Acronym for Lo ng Ra nge avigation. A system using pulsed, low frequency radio waves.
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 1,750-1,950 kHz frequency band. Loran C and D operate in the 100-110 kHz frequency band.
Abbreviation for: long range air navigation Fr: LORAN
Long range aids to navigation.
A short-range system for navigation that uses shore transmitters.
Long Range (navigation equipment)
A navigational system similar to GPS except based on ground transmitters, LORAN is relatively obsolete. The Letter M MSL. Mean sea level. Used by pilots when defining altitude, MSL refers to feet above sea level as opposed to above the ground. Pilots always use MSL when referring to altitude.

ong ange id to avigation - a ground-based transmitter system that was implemented in the late 1950s by the US government for navigational purposes. Loran is the general designation of a group of radionavigation systems by which a hyperbolic line of position is determined through measuring the difference in the times of reception of synchronized pulse signals from two fixed transmitters.
An electronic instrument using radio waves from various stations to find one's position. The LORAN system is being replaced by the GPS system and will be obsolete in a few years. Many LORAN stations have already stopped providing service.
LORAN (LOng RAnge Navigation) is a terrestrial navigation system using low frequency radio transmitters that use the time interval between radio signals received from three or more stations to determine the position of a ship or aircraft. The current version of LORAN in common use is LORAN-C, which operates in the low frequency 90 to 110 kHz band. Many nations are users of the system, including the United States, Japan, and several European countries.
