Long.Range.Navigation..A.system.using.a.ground. facility.composed.of.a.master.station.and.a. slave.station..The.airborne.receiver.computes. the.position.of.the.aircraft.by.using.two.or.more.
received master-slave pairs of signals. LORAN-A operates at 1850, 1900, and 1950 kHz. LORAN-C operates at 100 kHz. LORA N-A was replaced by LORAN-C in 1980.
