VHF Omnidirectional Range, or VOR, is a type of radio navigation system for aircraft. It operates in the VHF frequency band and provides pilots with information about their position relative to a specific point on the ground. The system emits signals that allow aircraft to determine their bearing from the VOR station, helping them navigate accurately. VOR stations are strategically located to cover large areas, and they are often used in conjunction with other navigation aids. Pilots can tune their instruments to the VOR frequency, allowing them to receive directional information and maintain their intended flight path.
