In navigation, a radio beacon or radiobeacon is a kind of beacon, a device that marks a fixed location and allows direction-finding equipment to find relative bearing. It is a fixed-position radio transmitter which radiates radio waves which are received by navigation instruments on ships, aircraft or vehicles.
The beacon transmits a continuous or periodic radio signal on a specified radio frequency containing limited information (for example, its identification or location). Occasionally, the beacon's transmission includes other information, such as telemetric or meteorological data.
