  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]
