SICRA: A GNSS cooperative system for avalanche rescue

This document presents a cooperative system based on GNSS (Global Navigation Satellite Systems) technologies for avalanche victims' rescue. The system includes the use of low cost user terminal comprising GNSS receivers and wireless network communications, relative navigation, and development of a control centre. System architecture and prototype is presented; an analysis of signal propagation in snow is presented, and finally results of on-site extensive test campaign in real snow conditions are discussed.
