Electric beacon
In navigation, an electric beacon (or electromagnetic beacon) is a kind of beacon, as a device which sends a signal and marks a fixed location and allows direction finding equipment to find relative bearing, as the direction to the beacon. The most common are radio beacons, which broadcast a radio signal which is picked up by radio direction finding systems on ships, aircraft or cars to determine the bearing to the beacon.[1] However, the term "beacon" also covers infrared and sonar beacons.
