Search and rescue operations in avalanches can greatly benefit from the support of unmanned aerial vehicles, which could safely and autonomously fly above the snow surface to estimate the position of the victim. This work relies upon the Appareil de Recherche de Victimes (ARVA), which consists of a transmitter and a receiver. The transmitter is worn by the victim and produces an electromagnetic field that can be sensed by the receiver, integrated on the drone. A receiver able to sense the complete 3D electromagnetic field has been developed, whose model and properties are presented in this work.

Abstract

Search and rescue operations in avalanches can greatly benefit from the support of unmanned aerial vehicles, which could safely and autonomously fly above the snow surface to estimate the position of the victim. This work relies upon the Appareil de Recherche de Victimes (ARVA), which consists of a transmitter and a receiver. The transmitter is worn by the victim and produces an electromagnetic field that can be sensed by the receiver, integrated on the drone. A receiver able to sense the complete 3D electromagnetic field has been developed, whose model and properties are presented in this work. The main contribution of this work is the development of a control algorithm able to drive the ARVA-equipped drone as close as possible to the victim location.
