Some airports are equipped with a VHF omnidirectional range ( VOR ) to help pilots find the direction to the airport.

* VHF omnidirectional range

VHF omnidirectional range, or VOR, is an implementation of the reverse-RDF system, but one that is more accurate and able to be completely automated.

* VHF omnidirectional range ( VOR )

During the second half of the 1960s several extensions, equipment upgrades like a VHF omnidirectional range ( VOR ) and an instrument landing system ( ILS ) as well as new buildings were constructed.

Navaids at the airport, such as the Instrument Landing System ( ILS ) and VOR ( VHF omnidirectional range ), are owned by the DAO but maintained by BAS-Serco.

In the process the Newcastle VHF omnidirectional range beacon was permanently withdrawn from service, since the new tower would have interfered with its operation.

Many GA aircraft are fitted with a variety of navigation aids, such as Automatic direction finder ( ADF ), inertial navigation, compasses, radar navigation, VHF omnidirectional range ( VOR ) and GNSS.

As the name implies, the signal transmitted does not include inherent directional information, in contrast to other navigational aids such as low frequency radio range, VHF omnidirectional range ( VOR ) and TACAN.

Today, the idea of a compass rose is found on, or featured in, almost all navigation systems, including nautical charts, non-directional beacons ( NDB ), VHF omnidirectional range ( VOR ) systems, global-positioning systems ( GPS ), and similar equipment and devices.

VHF omnidirectional radio range ( VOR ), is a type of short-range radio navigation system for aircraft, enabling aircraft to determine their position and stay on course by receiving radio signals transmitted by a network of fixed ground radio beacons, with a receiver unit.

DME frequencies are paired to VHF omnidirectional range ( VOR ) frequencies and a DME interrogator is designed to automatically tune to the corresponding DME frequency when the associated VOR frequency is selected.

Before the All-Channel Receiver Act of 1962 required US television receivers to be able to tune the entire VHF and UHF range ( which in North America was NTSC-M channels 2 through 83 on 54 to 890 MHz ), a set-top box known as a UHF converter would be installed at the receiver to shift a portion of the UHF-TV spectrum onto low-VHF channels for viewing.

However, most cable systems could not accommodate the full 54-890 MHz VHF / UHF frequency range and the twelve channels of VHF space were quickly exhausted on most systems.

" Vostok 1 passes out of VHF range of the Khabarovsk ground station and contact is lost.

Out of VHF range with ground stations, communications must now take place via HF radio.

* by frequency range ( audio, radio, VHF, UHF, microwave ),

For higher frequency antennas, in the VHF or UHF range, the ground plane can be smaller, and metal disks, screens or wires are used as ground planes.

This huge power level does not usually help to increase range as much as one might expect, because VHF frequencies travel in nearly straight lines over the horizon and off into space.

Very high frequency ( VHF ) is the ITU-designated range of radio frequency electromagnetic waves from to.

Common uses for VHF are FM radio broadcasting, television broadcasting, land mobile stations ( emergency, business, private use and military ), long range data communication with radio modems, amateur radio, marine communications, air traffic control communications and air navigation systems ( e. g. VOR, DME & ILS ).

VHF propagation characteristics are ideal for short-distance terrestrial communication, with a range generally somewhat farther than line-of-sight from the transmitter ( see formula below ).

For analog TV, VHF transmission range is a function of transmitter power, receiver sensitivity, and distance to the horizon, since VHF signals propagate under normal conditions as a near line-of-sight phenomenon.

Frequency assignments between US and Canadian users are closely coordinated since much of the Canadian population is within VHF radio range of the US border.

The receiver will also operate in the VHF and UHF range using either mixer image or alias responses.

An exciter provides of RF over the same range or into the VHF and UHF range using image or alias outputs.

Radio modem communication on UHF and VHF frequencies are widely used for short and long range communication within ITS.

Designed in 1937 at the Bureau of Air Commerce's research center, this system operated in the VHF band around 63 mHz and was an incremental improvement over prior aviation navigation systems such as the four-course radio range.

FM refers to frequency modulation, and occurs on VHF airwaves in the frequency range of 88 to 108 MHz everywhere except Japan and Russia.
