Loran
Loran Lor"an (l[^o]r"[a^]n or l[=o]r"[a^]n), n. [Acronym, from LOng RAnge Navigation] (Naut., aviation) 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] [RDH]
