radio beacons
Broadcast location signals
Radio beacons are transmitters that broadcast signals to help aircraft, ships, or vehicles determine their position or navigate toward a specific location.
The signal serves as an electronic landmark—pilots can home in on a beacon or use multiple beacons to triangulate position.
The plane followed the radio beacon through the fog.
Modern GPS has largely supplanted traditional radio beacons for navigation.
