U-space (RP2024)

(A.) Policy and legislation

(A.1)   Policy objectives

Drones are a promising source of innovative services for the society, from safer infrastructure inspections to more efficient transport and mobility solutions. Drones also offer an opportunity to green aviation and optimise deliveries. The aim of the Commission is to promote a transport system that is accessible, affordable, efficient, safe, secure and environmentally friendly and to create the conditions for a competitive industry generating growth and jobs. This is why, in perspective of the foreseen increase in drone traffic in Europe, the Commission’s Directorate-General for Mobility and Transport is addressing the safe operations and management of drone traffic in the wider context of aviation safety.

U-space is a set of new services relying on a high level of digitalisation and automation of functions and specific procedures, supported by AI, designed to provide safe, efficient and secure access to airspace for large numbers of unmanned aircraft, operating automatically and beyond visual line of sight. This initiative confirms the EU’s ambition to develop sustainable and digital mobility solutions..

(A.2) EC perspective and progress report

The impact of the digitalisation cannot be underestimated. Aviation moves from a human-centric system - where safety ultimately depends on pilots and air traffic controllers – towards an information-centric system, where highly automated aircraft can fly safely based on information flowing on mobile telecommunication networks.

As the aviation and mobile telecommunication worlds converge, the need for ICT standard will increase in aviation. This is particularly observable in the field of drones and unmanned aircraft traffic management solution, which are a laboratory for digital aviation solutions.

U-Space is such an unmanned aircraft traffic management solution which will allow the scaling up of the volume of drone operations that are complex, in environments that are challenging. This would include transport and mobility applications in urban environments, or close to airports.

On the basis of the Opinion 01/2020 published by EASA on a high-level regulatory framework for the U-space, the Commission has adopted three Implementing Regulations on a regulatory framework for the U-space. They cover the roles and responsibilities of the organisations involved in the definition of U-space airspace, the provision of U-space airspace services, including common information, and the minimum necessary services that need to be provided for unmanned aircraft in order to operate in the U-space airspace, the roles and responsibilities of Air Traffic Service Providers for the dynamic reconfiguration of airspace and the electronic conspicuity of manned aviation when entering a U-space airspace in non-controlled airspace.

On 29 November 2022, the Commission adopted its Drone Strategy 2.0 where it underlines the need to facilitate the roll-out of the initial U-space regulatory framework. To that end, U-space stakeholders should agree on the necessary protocols to exchange information and prioritise the development of the related standards.

For what standardisation concerns, the European Commission established the European UAS Standardisation Coordination Group (EUSCG), a joint coordination and advisory group coordinating the drone-related, including U-space, standardisation activities across Europe, and essentially stemming from the EU regulations and EASA rulemaking initiatives. The EUSCG was supported by the work of the AW-Drones Horizon 2020 project, which developed an open repository of unmanned aircraft standards and validated the suitability of technical standards to comply with existing regulation for drone operations. The resulting Drone Standards Information Portal is available online and is continuously maintained under an EASA contract.

(B.) Requested actions

Action 1: Based on the U-space regulatory framework, and in coordination with the European UAS Standardisation Coordination Group (EUSCG), standardise semantic and technical interoperability specifications to exchange U-space information and operational data:

  • between air navigation service providers, common information service providers and U-space service providers; and
  • between U-space service providers and UAS operators.

Action 2: The following complementary actions could be developed in addition to the standardisation action:

  • Development of a reference implementation of U-space software components to facilitate the adoption of U-space.
  • Development of a testing platform to assess whether the U-space interfaces developed by service providers comply with the standardised specifications.

(C.) Activities and additional information 

(C.1) Related standardisation activities

CEN/TC 377 'Air Traffic Management' has concentrated in the past on the introduction and update of EN 16495 “Air Traffic Management - Information security for organisations supporting civil aviation operations”. The standard represents a variant of the transversal ISO 27002 security standard. It adds a concept of evidence-based trust in the implementation of the security measures of the different stakeholders involved in air traffic management.

While U-Space represents a new discipline of airspace user management adding new “players” and thus new complexities, from a security point of view the fundamental approach of EN 16495 can be applied also with U-space regarding the integration of conventional ATM and U-space management.


IEEE has many efforts underway to develop standards for drones and UASs (Unmanned Aerial Systems): 

The Standards Committee: PE/T&D – ‘Power and Energy/Transmission and Distribution’ published a Guide for ‘Unmanned Aerial Vehicle-Based Patrol Inspection System for Transmission Lines’ (IEEE 2821-2020: )

 The ‘COM/AccessCore – Communication/Access and Core Networks’ Standards Committee published a Standard for ‘Interface Requirements and Performance Characteristics of Payload Devices in Drones’ (IEEE 1937.1-2020, )

The  Drone Remote ID Protocol (drip) WG  has recently formed in the IETF. Civil Aviation Authorities (CAAs) worldwide have initiated rule making for Unmanned Aircraft Systems (UAS) Remote Identification (RID). CAAs currently promulgate performance-based regulations that do not mandate specific techniques, but rather cite industry-consensus technical standards as acceptable means of compliance. One key standard is ASTM International (formerly the American Society for Testing and Materials) WK65041. This technical specification defines UAS RID message formats, and transmission methods. Network RID defines a set of information for UAS to be made available globally via the Internet. Broadcast RID defines a set of messages for UAS to send locally one-way over Bluetooth or Wi-Fi. WK65041 does not address how to populate/query registries, how to ensure trustworthiness of information, nor how to make the information useful.

DRIP’s goal is to specify how RID can be made trustworthy and available in both Internet and local-only connected scenarios, especially in emergency situations. Some UAS operate in environments where the network or the devices or both are severely constrained in terms of processing, bandwidth (e.g., Bluetooth 4 beacon payload is 25 bytes long), or battery life, and DRIP aims to function in these environments. The specifications produced by the WG will need to balance public safety authorities’ need to know trustworthy information with UAS operators’ and other involved parties’ privacy.

The working group will primarily leverage Internet standards (including HIP, EPP, RDAP, and DNS) and infrastructure as well as domain name registration business models. The WG will track and align with the requirements being developed by regulatory authorities, e.g., the International Civil Aviation Organization the European Union Aviation Safety Agency (EASA) delegated and implementing regulations, and the US Federal Aviation Administration (US FAA).
