The research on Unmanned Aircraft Systems (UAS) is experiencing rapid growth. At the Future UAS Technologies Workshop, technology pioneers in this field are introducing their work. In the course of this event the Meteomatics GmbH presents the Meteodrone System. This system, developed in cooperation with MeteoSwiss and funded by the Federal Office of Civil Aviation, may not only improve predictions of fog and thunderstorms, but can also measure environmental data like fine dust, ozone, and NO2.
