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
Prebuilt
DIY
- Loop Antennae
- Rhomboid Antennae
Provides
- Easy DIY GPS Like Navigation in Under-served Areas
- Redundancy to GPS Navigation
- Possibly Cheaper, Simpler, and More Precise Navigation (All that is needed for reading could be as simple as an antennae and an oscilloscope for manual, or a simple Arduino circuit and an antennae for automatic
- Benefits Automation like the Open Source Robotic Tractor
