Which frequency is used in the VOR system?

The VOR (VHF Omnidirectional Range) system operates in the Very High Frequency (VHF) band, specifically within the frequency range of 108.0 to 117.95 MHz. This frequency allocation allows for reliable signal transmission and reception, which is critical for aircraft navigation.

VOR provides pilots with accurate bearing information by transmitting signals in all directions from a fixed ground station, allowing aircraft to navigate by determining their position relative to these signals. The use of VHF frequencies is advantageous because they offer better line-of-sight propagation, less interference, and improved clarity of signals compared to lower frequency ranges. The characteristics of VHF meet the precise requirements for the VOR system, making it an integral tool in aviation navigation.
