Loran (LOng RAnge Navigation) is a terestrial based, parabolic, radio navigation sysytem that uses the time difference in radio pulses recieved from radio towers in a chain to determine position. Generally three towers are used to get a fix.

Where GPS works on satellites, LORAN works on land based radio towers. It doesnt work too far out to sea, and it does not work in a river channel between high cliffs. Otherwise it still works. We were in a situation off Block Island where the compass read 45 degrees off our LORAN, it was the current. We believed the LORAN and got to Cuddyhunk. Now we have a copy of Captain Eldridges Tides and Currents. The boat compass told the direction the boat was pointing and the LORAN told the direction the boat was moving.

It picks up the signals from 3 stations and triangulates the bearings to the signals to locate your position. Military aircraft stopped using this system years ago. I worked on it in the shop and on the C130. Many military aircraft that had Loran on them went to Omega, then removed that with the advent of GPS.
