White Paper
Validation of Integrated Multi-stakeholder Architecture for UAS Traffic Management
GOF 2.0 Integrated Urban Airspace

The number of air operations over cities is expected to increase over the next 5-10 years. Already now, manned and unmanned aircraft share the skies at low level with helicopters and drones operating in mixed airspace over cities and elsewhere below 500 feet. GOF2.0 demonstrated a unified air operation traffic management with high levels of automation serving both manned and unmanned aircraft in a safe, interconnected, distributed, interoperable, efficient, scalable and environmentally optimized manner. Highly automated separation assurance in dense airspace – specifically in areas where urban mobility and aerodrome traffic is expected – is becoming a critical capability to efficiently manage a unified airspace. Integrated trajectory management service based on flight plan information and real-time surveillance combined with a digitally connected environment provide the basic safety net for all aviators.

The main objective of GOF2.0 was to build on GOF USPACE project and other SESAR projects to validate the orchestration and operation of available state-of-the-art COTS components and services to create a dynamic operating environment for manned and unmanned aircraft to operate safely in a shared airspace along with the provision of enhanced safety net/deconfliction functionalities to maintain separation between aircraft and to lower air and ground risks.

GOF 2.0 is managed by the SESAR 3 Joint Undertaking in an effort to deliver solutions for U-space, the European Commission’s initiative on the safe and secure integration of drones in European airspace.

This project has received funding from the SESAR 3 Joint Undertaking under the European Union’s Horizon 2020 research and innovation programme under grant agreement No 101017689.

The SESAR 3 Joint Undertaking is an institutionalised European partnership between private and public sector partners set up to accelerate through research and innovation the delivery of the Digital European Sky. To do so, it is harnessing, developing and accelerating the take-up of the most cutting-edge technological solutions to manage conventional aircraft, drones, air taxis and vehicles flying at higher altitudes. The SESAR 3 JU partnership brings together the EU, Eurocontrol, and more than 50 organisations covering the entire aviation value chain, from airports, airspace users of all categories, air navigation service providers, drone operators and service providers, the manufacturing industry and scientific community. The partnership also works closely with the regulatory and standardisation bodies, notably EASA and Eurocae, as well as key stakeholders, such professional staff organisations, the space and military communities and global partners.

Airbus Urban Mobility GmbH was founded in May 2018 in order to take our exploration into cutting-edge commercial urban air mobility solutions and services to the next level. We are exploring how recent technology advancements provide mobility solutions and services – from battery capacity and autonomy to electric propulsion – that can help drive the development of new kinds of aerial vehicles (eVTOLs). Airbus Urban Mobility focuses on better connecting people by bringing the safety, convenience and joy of flight to city inhabitants. To make this a reality, we’re architecting all pieces of the urban air mobility domain. Our approach includes building and bringing together all the relevant components—technology, business models, city integration, infrastructure development, and airspace management – to take urban transport into the sky. In doing so, we can ensure maximum societal benefits for urban communities worldwide.
