Service for providing aeronautical information/data necessary for the safety, regularity, and efficiency of aviation (e.g., NOTAM, AIP).

Part of ATM responsible for sequencing/coordination in controlled airspace. In U-space airspaces within controlled airspace, coordinated procedures (e.g., dynamic airspace configuration) are crucial.

Organization that provides air traffic control or air navigation services (e.g., air traffic control, flight information, navigation services). In U-Space, coordination and data exchange between ANSP and USSP are regulated.

All functions and services for the safe, orderly, and efficient handling of air traffic (including ATC, airspace, and flow management). UAS integration (e.g., U-Space/UTM) must take into account interfaces with ATM.

ICAO concept for the (near) real-time organization, coordination, and management of many UAS operations—especially in low airspace and also for BVLOS—through digital services and cooperation between authorities/ANSPs/industry.

Service levels from SESAR U-Space development: U1 (Foundation: e-registration/e-identification/geofencing), U2 (Initial: flight planning/clearance, tracking, ATC interface), U3 (Advanced: conflict support/more automation), U4 (Full: highly automated operations in very dense environments).

Optional U-Space service that supports UAS operators in planning and execution with weather information, thereby also improving the quality of other U-Space services.

Optional U-Space service that detects/warns of deviations from the issued UAS flight authorization in real time and informs the operator of non-compliance.

U-Space service that warns or informs UAS operators about other air traffic in the vicinity of their UAS in order to avoid conflicts.

U-space service that coordinates UAS flight authorizations in U-space and ensures that authorized UAS operations within the U-space area in question do not collide with each other in terms of space and time.
