Very high frequency omnidirectional range

Having to understand what Very high frequency omnidirectional range is used for may not be new to us, as this could be due to the reason being that we all communicate with our different gadgets.


Yes, just like our phones which transmit frequencies, this instrument also does so in the aviation sector. but who is this done and why is it called VHFOR?


This article is aimed at explaining to you these words in its meaning, synonyms, antonyms, translations and use cases.



Very high frequency omnidirectional range / veri haɪ ˈfriː. kwə o’mɪn.idaɪˈrek.ʃən.əl reɪndʒ / is a type of range which enables aircraft equipped with a receiving unit to locate itself and maintain its course by picking up radio signals emitted by a series of fixed ground radio beacons.


VHF Omnidirectional Radio Range (VOR) is a term used to refer to an aircraft navigation system that uses the VHF frequency range.


Other meaning

The omnidirectional VHF radio spectrum (VOR) is the fundamental form of electronic navigation currently in use. The ground-based transmitters are necessary for this VHF Omni-Range navigation system.


The omnidirectional VHF radio spectrum is an omnidirectional (360 degrees of azimuth) range station that uses the very high frequency (VHF) band of the radio spectrum, between 108 and 118 MHz. It shares the band with the localizer part of the Instrument Landing Systems from 108 to 112 MHz (ILS).

Many languages have a pronunciation to these words, but here we will take a look at some of the ways some world languages pronounce it.

French: Portée omnidirectionnelle très haute fréquence

Serbian: Веома високофреквентни омнидирекциони опсег (Veoma visokofrekventni omnidirekcioni opseg)

Slovak: Veľmi vysokofrekvenčný všesmerový rozsah

Chinese: 甚高频全向范围 (Shèn gāopínquán xiàng fànwéi)

Swahili: Masafa ya uelekezaji wa masafa ya juu sana

Latin: Altissima frequentia omnidirectional range


Use cases

As a progression of Visual-Aural Range (VAR) systems, Very High Frequency Omni-Directional Range (VOR) was originally introduced in the 1950s.


The VORs transmit a VHF radio composite signal that contains information that enables airborne receiving equipment to determine the magnetic bearing from the station to the aircraft as well as the station’s Morse Code identifier (and occasionally a vocal identifier).


Instead, the VOR radial can be utilized in conjunction with the magnetic heading from the aircraft compass to generate a bearing relative to the aircraft axis that can be used to home to the beacon.


For ground-to-air communication, a voice channel may also be offered to the VOR. VOR is ground equipment. Utilizing VORs across Very High Frequency (VHF)


The Visual-Aural Range (VAR) systems gave way to the Very High Frequency Omni-Directional Range (VOR), which was originally introduced in the 1950s.


Frequently Asked Questions


What is the main underlying operating principle of the Very High Frequency Omnidirectional Range VOR aircraft navigation system?

What is the Very-high-frequency Omnidirectional Range (VOR) aircraft navigation system’s fundamental guiding principle? It is possible to determine an aircraft’s azimuth position in reference to a particular VOR station by comparing the phases of two AC voltages.


What are the limitations of VOR?

VORs can only be used in line-of-sight. Signals from VOR are interfered with by barriers, topography, and even the slope of the earth. The number of aircraft that can use a single VOR at once is unrestricted. VORs are divided into three categories: Terminal (T), Low (L), and High (H) (H).


What is the lowest frequency that VOR can use?

VORs work in the frequency range of 108.0 to 117.95 MHz and have the power output required to provide coverage inside the designated operating service volume. They are restricted by line-of-sight, and the range varies inversely with receiving equipment altitude.


How many channels are available for VOR?

VOR are used in the 108 to 117.95 MHz Very High Frequency (VHF) band with channels spaced at 50 or 100 kHz (50 kHz for dense zones, 100 kHz elsewhere). The first 4 MHz is shared with the ILS (Instrument Landing System) band, and 160 of the 200 available channels are designated for the VOR.



VOR navigation technique sends a directional signal that rotates 360 degrees in azimuth or 30 times clockwise at a station using a ground-based antenna. Along with the directional signal, a reference signal is also released at the exact moment magnetic north is reached.
