  • Low-frequency signals (100 kHz) penetrate better and require massive power to jam over a wide area.

  • Ground-based transmitters can broadcast over hundreds of miles, making them more robust than satellite-based signals.

  • Complementary use with GPS can harden systems against spoofing and outage.

I live not too far a jaunt from the old Gulf of Buc-ee's (was that the name?) LORAN master control station. It was in Marianna, FL, built on an old WWII B-29 training base auxiliary air field. It's long decommissioned and gone now. There'd be much infrastructure to rebuild. Ok, all infrastructure. But it was a good system in its day.

I remember visiting the station as a kid. You could put your ear to the entry gate and hear the signal reverberation in the metal. There was that much power.

I probably got fixes from that station.

I remember the old receivers, looking at two signals and lining up the pulses. The resulting number was one of the LORAN lines on the chart.
