NDB (Non-Directional Beacon)

An NDB (Non-Directional Beacon) is a ground-based radio transmitter used in aviation navigation. It emits radio signals in all directions, allowing aircraft equipped with a special receiver to determine their position relative to the beacon. Pilots interpret these signals to find their way, especially in areas without advanced navigation systems. While NDBs are reliable and cost-effective, they are gradually phased out in favor of modern navigation technologies like GPS. Overall, NDBs serve as important navigational aids, helping pilots maintain course and reach their destinations safely.
