The global objective of AURA is to lay the foundations for the integration of the new entrants in current and future air traffic environment, developing the required concept of operations and validating U-space services information exchanges with ATM systems. In order to achieve this objective, all relevant stakeholders (drone operators, U-space service providers, data services providers, ATM providers and authorities) will be included during the project development and throughout its lifetime. AURA project will identify the requirements for U-space information exchange with ATM through SWIM and will validate a set of selected U-space services, developing the service definition for the SWIM candidate services. Secondly, it will define a novel Collaborative ATM-U-space Concept of Operations (ConOps) for drones in a fully collaborative environment with ATM that go beyond the existing concepts developed for a U-space and will validate these new concepts. AURA project will contribute to enable the development of Very Low Level (VLL) markets, allowing the introduction of new actors in a safe, harmonized, sustainable and efficient way and compatible with current ATM environment. Also, the project will contribute to avoid the segregation of the airspace and increase the interoperability. AURA will provide inputs for the current regulatory and standardization initiatives regarding U-space with a high involvement of external stakeholders through an Advisory Board.
