Abstract
The project “BLUESLEMON” aims to develop a low-cost automatic system for monitoring landslide
surface displacement through the integration of Bluetooth (BT) Beacons localization and UAS also
named Remotely Piloted Aircraft System (RPAS) technologies. Two subsystems will assemble the
final setup: the ground sensors technology and the periodic localization system composed by UAV
and beacon reader. These are designed as an inseparable integrated architecture and each
individual subsystem cannot operate on the supposed landslide areas without the cooperation of
the other one. Thus, a main challenge consists in the identification of low-power-consumption and
high-precision Bluetooth devices, as well as in the development of a UAV platform capable to work
even at a limit of feasibility considered for an Alpine scenario (e.g. -20 °C at 2500 m asl). To prevent
undesirable collisions with surrounding structures (e.g. trees, powerlines and funicular railways),
the UAV platform will be equipped with obstacle-detection sensors and collision-avoidance
algorithms.
