LORAN-C

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. Before the popularity of the satellite-based GPS system, it was primarily used in marine applications. The current version of LORAN in common use is LORAN-C, which operates in the low frequency 90 to 110 kHz band.
