Loran-C - Introduction (original) (raw)

Users can return to previously determined positions with an accuracy of 18 to 90 meters using Loran-C in the time difference repeatable mode. Advances in technology have allowed greater automation of Loran-C operations. New technology has allowed the United States Coast Guard to establish centralized control of the continental U.S. Loran-C system at two locations. The application of new receiver technology has improved the usability of the system. A majority of the 1.3 million Loran sets in use worldwide are for mariners. Loran-C is greatly appreciated by the US general aviation community with some 80,000 aircraft now equipped with the system. For further details, please select one of the following catagories:

Loran-C operates in the 90 to 110 khz band, uses pulse-time and phase-difference as its operating principle and the day/night range is 1200/2400 nm typical.
