VOR Monitor RNAV

The signal from a VORVOR —VHF Omnidirectional Range is improved through the use of a ground monitor at the station. If either the signal direction or signal strength become suspect, the monitor will remove the navigational and ident components from the VORVOR —VHF Omnidirectional Range, or stop the VORVOR —VHF Omnidirectional Range transmitting at all. The accuracy that the monitor requires of the ground equipment is ±1°.
