A very high frequency omnidirectional range station (VOR) [1] is a type of short-range VHF radio navigation system for aircraft, enabling aircraft with a VOR receiver to determine the azimuth (also radial), referenced to magnetic north, between the aircraft to/from fixed VOR ground radio beacons.
Most VORs have distance measuring equipment (DME) or tactical air navigation equipment (TACAN) installed within the VOR station. When a VOR is collocated with DME, it's labeled as "VOR-DME." On the other hand, when a VOR is collocated with a TACAN, it's called a VORTAC.
What Does VOR stand for? The VHF omnidirectional Radio Range or VOR is an aircraft navigation system that functions to operate in the VHF band. VORs are the most common ground-based navigational aid. They are actually older than GPS, and they were used in the 1960s when GPS had not been invented.
