Ensuring a scalable, flexible and cost efficient system, IMPETUS proposes the application of the Function as a Service paradigm and Smart Concepts. Concurrently, data quality and integrity is taken into account to guarantee a safe conduct of all operations. To fulfil these purposes, the project started to characterize data processes and services of vital importance for drone operations. Following the requirements derived from this preliminary studies, a Smart UTM Design is drafted in alignment with the U-Space concept, which describes a framework for a progressive implementation of services to "enable complex drone operations with a high degree of automation to take place in all types of operational environments, including urban areas". Subsequently, specific microservices will be prototyped and laboratory scale tested in a server-less cloud-based environment.
