LORAN-C was a radio navigation system which allowed a receiver to determine its position by listening to low frequency radio signals transmitted by radio beacons. 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. This Technology Benefits OSE by allowing Open Source and Relatively Simplistic Navigation Technology for things such as the automated tractor. It was used for navigation before GPS, but then declined in usage.  It is predicted to have a resurgence due to  the need for a GPS alternative for redundancy. Also a new version has been explored called eLORAN which uses more modern systems for improved accuracy.

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)
