Ensure your safety in the backcountry with our top-rated avalanche transceivers. Fast, reliable, and easy to use.
An avalanche transceiver or avalanche beacon is a type of emergency locator beacon, a radio transceiver (a transmitter and receiver in one unit) operating at
Abstract—This contribution outlines an experimental setup and methodology employed to extensively characterize LoRa propagation in the demanding scenario of avalanche search and rescue (SaR),
In this work, we explore the potential of LoRa technology under challenging realistic conditions. For the first time, we collect radiopropagation data and the contextual snow profile when
It can support the development and benchmarking of positioning methods based on LoRa signal strength and, more broadly, the design of resilient SaR communication systems for avalanche-prone
ABSTRACT: The standardized frequency for avalanche transceivers, 457 kHz, presents many interest ing, important, and confusing issues, especially related to receive range, flux lines, near field, interfer
Nowadays, searching with avalanche transceivers is the only reliable method for locating a completely buried victim immediately after an accident. The present work is firstly focused on the
This contribution outlines an experimental setup and methodology employed to extensively characterize LoRa propagation in the demanding scenario of avalanche search and rescue (SaR), where the
An avalanche transceiver is an essential part of any backcountry skiers equipment. This guide gives you all you need when looking at avalanche beacons.
In avalanche scenarios, the snow depth and the snowpack profile significantly influence the wireless propagation of technologies used to locate victims, such as ARVA (in French: appareil de recherche
Before, it seems essential to recall some of the principals about avalanche rescue and the electromagnetic field of avalanche transceivers with a frequency of 457 kHz.
Venturing into the heart of avalanche search and rescue (SaR), our mission was clear: to study the potential of LoRa technology in localizing targets buried under an avalanche.
Hier sollte eine Beschreibung angezeigt werden, diese Seite lässt dies jedoch nicht zu.
In this context, Avalanche Transceiver Devices (ARTVA) have been adopted for many years to locate mountain enthusiasts involved in avalanche incidents. These tools have gained widespread use
The dataset aims to assess the ability to locate a victim in an avalanche scenario. The collected data allow for the evaluation of the quality of the LoRa signal in various environmental
This groundbreaking study explores the potential of #LoRa (Long Range) technology to revolutionize Search and Rescue (#SaR) operations in challenging avalanche scenarios.
A LoRa-based system for SaR operations is presented and analyzed. The localization of the persons is obtained through an algorithm based on path loss measurements.
Overview: The dataset contains measurements of Received Signal Strength Indicator (RSSI) and Signal-to-Noise Ratio (SNR) collected from Long-Range (LoRa) devices in avalanche
For over 30 years, ARVA has focused on designing and developing avalanche transceivers. We continue to innovate to make searches simple and easy,
Home » Blog » Outdoor Gear » Avalanche transceiver: functions and how to use Also known as a beacon, an avalanche transceiver works by using a
Abstract Background: Avalanche transceivers are essentials tools in locating persons who were buried by an avalanche. In the past few years, avalanche transceivers have become widely available and
The dataset presented in this article explores the feasibility and the performance of LoRa (Long Range) technology on board of a UAV for use in SaR scenarios. The transmitter was buried in snow across a
Comprehensive technical guide to avalanche transceivers: 457 kHz operation, antenna systems, search phases, multiple burial handling.
