UAS Traffic Management (UTM) is a subject rapidly gaining importance in the context of UAS Integration into the airspace System. Various initiatives like from FAA/NASA, SJU, GUTMA, EUROCAE, and LUFO have been started to look at the concept of operations, top level requirements, system decomposition , interfaces, resources, and neighbouring systems like ATM, Surveillance etc. The paper presents the DFS activities in these areas, the perspective of an ANSP on UTM, the similarities, differences, and interconnections between UTM and ATM, and the strategy of the DFS towards future UTM solutions. Specific consideration is given to surveillance, tracking/MSDF issues, mission plan issues, data modelling and Interfaces.
