lo·ran (lôr  n , l r-)n. A long-range navigational system in which position is determined by an analysis involving the time intervals between pulsed radio signals from two or more pairs of ground stations of known position. [lo(ng-)ra(nge) n(avigation).] |
loran [ˈlɔːrən]
n
(Mathematics & Measurements / Navigation) a radio navigation system operating over long distances. Synchronized pulses are transmitted from widely spaced radio stations to aircraft or shipping, the time of arrival of the pulses being used to determine position

| loran (lôrn) A long-range navigational system, in which a receiver's position is determined by an analysis involving the time intervals between pulsed radio signals from two or more pairs of ground stations of known position. The difference in the timing of the received signals corresponds to differences in distance from the transmitters, and the position of the receiver can be calculated by triangulation. Compare Global Positioning System. |
A long-range radio navigation position fixing system using the time difference of reception of pulse type transmissions from two or more fixed stations. This term is derived from the words long-range electronic navigation.
