Basics

  • LORAN-C was a radio navigation system before GPS which allowed a receiver to determine its position by listening to low frequency radio signals transmitted by radio beacon base stations.
  • They essentially sent out blips like GPS, and the device did the calculation based of the beacons' prerecorded location, and the time delay of the different signals.
  • A new version has been explored called eLORAN which uses more modern systems (Such as networking between radio base stations for time syncing, and error correction for improved accuracy.

Frequencies Used

  • Loran-C operated in the 90 kHz to 110 kHz frequency range (This is commonly categorized as "Low Frequency" a group from 30 kHz to 300 kHz)

Possibly Antennae

DIY

  • Loop Antennae
