What is meant by the aviation term VOR?

VOR stands for VHF Omnidirectional Range, a type of radio navigation system for aircraft. It provides pilots with a way to determine their position and stay on course by receiving radio signals from ground-based VOR stations. These stations transmit signals in all directions, allowing pilots to use their onboard instruments to navigate by following specific radials. VOR is a critical component of modern air traffic control and helps ensure safe and efficient flight operations.
