VOR, typically represented as an acronym, stands for Very High Frequency Omnidirectional Range. This radionavigation system provides aircraft with magnetic bearing information relative to a ground station. A pilot uses this bearing, along with distance measuring equipment (DME), to determine position and navigate. VOR stations transmit radio signals that allow an aircraft’s receiver to calculate its bearing from the station.
The system is a cornerstone of air navigation, particularly for instrument flight rules (IFR) operations. Its widespread adoption offers consistent and reliable guidance for pilots, increasing flight safety and efficiency. Developed in the mid-20th century, it became an internationally recognized standard, replacing earlier, less accurate systems. Its robust design and relative simplicity contribute to its ongoing utility in civil aviation.
