The avalanche beacon is an active device powered by batteries; a ski suit may also contain a passive RECCO transponder sewn into the clothing. Early avalanche transceivers transmitted at 2.275 kHz. [2] In 1986, the international frequency standard of 457 kHz was adopted, and this remains the standard today. [3]
An emergency locator beacon is a radio beacon, a portable battery powered radio transmitter, used to locate airplanes, vessels, and persons in distress and in need of immediate rescue. Various types of emergency locator beacons are carried by aircraft, ships, vehicles, hikers and cross-country skiers.
Avalanche Transceivers — known as beacons, "beepers", peeps (pieps), ARVAs (Appareil de Recherche de Victimes en Avalanche, in French), LVS (Lawinen-Verschütteten-Suchgerät, Swiss German), or various other trade names, are important for every member of the party. They emit a "beep" via 457 kHz radio signal in normal use, but may be switched ...
On Saturdays at a backcountry warming hut used by snowmobilers, avalanche educators give basic rescue lessons including how to use avalanche beacons — transmitters that send a signal rescuers ...
An avalanche killed four skiers and injured four others Saturday in a popular recreation area, making it one of the deadliest avalanches in Utah history, authorities said. The Unified Police ...
An avalanche swept up skiers at Lake Tahoe's largest ski resort on Jan. 10, 2024, as a 150-foot-wide sheet of snow slid down a mountain slope into a pile 10 feet deep.
Avalanche transceivers operate on a standard 457 kHz, and are designed to help locate people and equipment buried by avalanches. Since the power of the beacon is so low the directionality of the radio signal is dominated by small scale field effects [15] and can be quite complicated to locate.
Blue force tracking (BFT) systems consist of a computer, used to display location information, a satellite terminal and satellite antenna, used to transmit location and other military data, a Global Positioning System receiver (to determine its own position), command-and-control software (to send and receive orders, and many other battlefield support functions), and mapping software, usually ...
