VHF OMNIDIRECTIONAL RANGE
Portée omnidirectionnelle VHFsystem combining ground-based and airborne equipment wich provides the magnetic bearing QDR elabored by a ground based transmitter.
two 30 Hz BF signals : a 30 Hz reference signal, which phase is dependent from the azimuth and a 30 Hz variable signal, which difference in phase with respect to the 30 Hz reference signal is equal to the azimuth of the transmitted signal.
.160 channels frequency range from 108 to 118 MHz (VHF band)
.2 to 3 letter ident, amplitude modulated
operational range : 200 NM
VOR ground facilities are usually co-located with a DME ground station.
