An 'omnirange' is a type of radio navigation system used by aircraft. It emits radio signals in all directions, allowing pilots to determine their position and bearing relative to the station. Think of it as a radio-based GPS for airplanes. It provides pilots with crucial navigational information, especially in areas where GPS might be unreliable. It utilizes VHF (very high frequency) radio waves. It is a vital component of air traffic control and aviation safety.
