For over 50 years, CEC has been producing low frequency (LF) transmitters, which power eLORAN technology. With hundreds of transmitters deployed around the world; no other manufacturer has delivered more LF transmitters.
For over 30 years, Microsemi has delivered timing products to the USG and national critical infrastructure operators, including the Time and Frequency Equipment (TFE) used in the updated LORAN-C transmitter stations in the US and over 95% of the domestic commercial telecommunications markets.
In a hyperbolic system like LORAN, a receiver on an aircraft or ship picks up radio signals broadcast by one or more pairs of radio stations spaced hundreds of miles apart. The system works by measuring the time difference between signals from the two stations. By tuning in different pairs, the navigator could plot lines of position in the form of hyperbolas (arcs) that intersect to give precise location.
PUTTING THE LONG RANGE IN LORAN
LORAN receivers picked up signals that were either broadcast directly from stations as "ground waves" or reflected as "sky waves." Sky waves could travel three times farther than ground waves because they reflect off the ionosphere, the layers of charged particles in Earth's upper atmosphere.
