Ensuring the safe separation of aircraft is a core function of air traffic management (ATM) today. As the number of unmanned aerial vehicles (UAVs) increases, effective separation management between these newcomers and traditional aviation becomes crucial to maintaining airspace safety.
The SESAR-supported SPATIO project delivers separation management services that enable drones to operate safely and simultaneously in very low-level airspace. SPATIO addresses conflict resolution both before take-off, through strategic conflict resolution services, and during flight, via tactical conflict resolution. These separation services are fundamental to U-space, Europe’s unmanned traffic management (UTM) system, which aims to control, manage, and integrate all drones—initially in very low-level airspace and eventually at higher altitudes. By uniting industry, ANSPs, institutions, and universities, SPATIO moves beyond isolated research efforts to develop a coordinated, integrated separation management solution for drones.
Additionally, SPATIO lays the groundwork for fairness principles that establish priority mechanisms for UAS operators, moving beyond the conventional "first come, first served" approach, which does not always meet operators' expectations.
SPATIO also integrates separation services with dynamic capacity management, monitoring airspace capacity and demand. This monitoring determines the maximum number of UAS that can safely operate, considering risks to the population and environmental impacts such as noise.
Furthermore, SPATIO advances automation in separation management by developing a ground-based safety net capable of issuing direct commands to drones if pilots fail to respond to instructions.
SPATIO’s solutions will be validated in four real-world environments across Spain, Ireland, and Romania. The system architecture aligns with Europe's vision of multiple U-space service providers operating within the same airspace—even for tactical separation—a significant step forward from traditional aviation practices. These advancements will impact the entire drone ecosystem, including UAS manufacturers, operators, and service providers, fostering market growth and benefiting existing airspace users. Additionally, SPATIO will provide valuable insights for the future development of the ATM industry.
Beyond operational advancements, SPATIO will provide valuable insights into regulatory and standardization needs, as well as the costs and benefits of implementation.
Ultimately, SPATIO will enhance the safe and secure integration of UAS operations in high-risk areas such as airports and urban environments, contributing to broader societal acceptance of drone operations.
