bilinen bir coğrafik lokasyonda sabitlenmiş (radyo) vericiyi esas alarak mesafe farklılıklarını ölçmede kullanılan bir hiperbolik navigasyon (denizcilik) sistemi
(Askeri) UZUN MENZİLLİ MEVKİ TAYİN SİSTEMİ: İki veya daha çok sabit istasyondan yapılan sinyal şeklindeki yayının zaman farkını kullanarak mevki tayin imkanı veren hiperbolik uzun menzilli bir seyir sistemi (Bu terim long-range electronic navigation sözcüklerinin ilk hece veya harflerinden türetilmiştir)
loran teriminin İngilizce İngilizce sözlükte anlamı
Long range aid to navigation Operates off of (3) land based radio towers to triangulate location
abbreviation of long-range navigation A land-based system of radio navigation in common use over the continental United States and in its coastal waters. It was developed during World War II for the U.S. military. A civilian version, Loran-C, was developed in the 1950s. Loran-C can be used to determine position within about 30 ft (10 m) by comparing signals from multiple stations. Loran-like systems operate in many coastal waters around the world. However, the availability of the global positioning system (GPS), with a typical accuracy of 3 ft (1 m), has begun to relegate loran to backup status
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)
A navigational system similar to GPS except based on ground transmitters, LORAN is relatively obsolete
Long Range Navigation, a system of long range navigation whereby latitude and longitude are determined from the time displacement of radio signals from two or more fixed transmitters
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
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
