radio beacon


radio beacon
Fixed ground stations emitting RF (radio frequency) signals, especially those containing identification signals such as NDBs (nondirectional beacons), which enable aircraft to fix their position relative to them. These facilities normally operate in the frequency band of 190 to 535 kilohertz (kHz) and transmit a continuous carrier with either a 400 or a 1020 hertz (Hz) modulation. All radio beacons except the compass locators transmit a continuous three-letter identification in code, except during voice transmissions. When a radio beacon is used in conjunction with the instrument landing system markers, it is called a compass locator. Voice transmissions are made on radio beacons unless the letter W (without voice) is included in the class designator. Radio beacons are subject to disturbances that may result in erroneous bearing information. Such disturbances result from such factors as lightning, precipitation, static, etc. At night, radio beacons are vulnerable to interference from distant stations.
