Radio beacon

In navigation, a radio beacon is a kind of beacon, a device that marks a fixed location and allows direction-finding equipment to find relative bearing. Radio beacons transmit a radio signal that is picked up by radio direction-finding systems on ships, aircraft and vehicles to determine the direction to the beacon.

Radio beacons transmit a continuous or periodic radio signal with limited information on a specified radio frequency. Occasionally, the beacon's transmission includes other information, such as telemetric or meteorological data.
