LORAN - Wikipedia
LORAN (Long Range Navigation) [a] was a hyperbolic radio navigation system developed in the United States during World War II. It was similar to the UK's Gee system but operated at lower frequencies in order to provide an improved range up to 1,500 miles (2,400 km) with an accuracy of tens of miles.
Loran-C - Wikipedia
Loran-C is a hyperbolic radio navigation system that allows a receiver to determine its position by listening to low frequency radio signals that are transmitted by fixed land-based radio beacons. Loran-C combined two different techniques to provide a signal that was both long-range and highly accurate, features that had been incompatible.

Why Was LORAN Such a Milestone? | Time and Navigation
With LORAN, navigators went from using mechanical-based time measured in seconds to using radio frequency-based time measured in microseconds (millionths of a second).
eLoran - Wikipedia
Enhanced LORAN (commonly known as eLoran; also known as eLORAN, E-LORAN, or e-LORAN) is a long-range radio navigation system that uses terrestrial towers and the hyperbolic navigation technique. It is an advancement in receiver design and transmission characteristics which increase the accuracy and usefulness of traditional LORAN and LORAN-C .
