ICAS, the International Council of the Aeronautical Sciences, ist a non-profit scientific organization with the mission to advance knowledge and facilitate collaboration in aeronautics. Some events such as international conferences or workshops are organized by ICAS. One of these events takes place in Winterthur from 11th - 12th of September. The aim of this workshop is to talk about Intelligent and Autonomous Technologies in Aeronautics Software Engineering and UAS. For this reason many experts, like Dr. Martin Fengler, CEO of Meteomatics, were invited. Due to the fact that Meteomatics is the first swiss company to develop a weather drone, Dr. Fengler`s speech contains the idea of an Operational Drone Network for Weather Measurements.
