Monitoring of larger areas for the verification of the avalanche forecast and avalanche control as well as early warning of increasing avalanche activity.
|Operating principle||Avalanche produce infrasound waves below 20 Hz (not audible for humans), which are detectable for sensor over large distance. Thanks to a sophisticated algorithm, noise signals can be filtered and avalanches detected.|
|Setup||3 sensors installed in a triangle setup with a distance in between of approx. ca. 100 m and one sensor in the centre. This array is installed outside of the avalanche path and connected to a central computer where the data is transmitted to a server for the analysis. Thanks to snow coverage of the sensors, higher frequent noise signals are filtered out.|
|Range||up to approx. 5 km|
|Data transfer||Mobile network, Ethernet|
|Power supply||Electricity grid, solar or fuel cell|
