Abstract
The Nordkette laboratory has been home to various aspects of avalanche research due to its proximity and accessibility. Lately performed inflow avalanche measurements at the Nordkette laboratory were evaluated to investigate the internal dynamics of avalanches and provide data to test corresponding simulation models. The used measuring system, called AvaNode, and improved algorithms showed promising results regarding motion reconstruction. The AvaNode measures translational acceleration, angular velocity, magnetic flux density by means of an IMU (Inertial Measurement Unit), as well as GNSS (Global Navigation Satellite System) position and translational velocity. In avalanche experiments with the AvaNode, the start- and end-point as well as the velocities of this particle can be extracted from the GNSS data. Additionally, the particle trajectory is approximated by means of the IMU data.
