EUROCONTROL is a pan-European, civil-military international organisation dedicated to supporting European aviation for the Safety of Air Navigation. It has 41 Member States and is headquartered in Brussels. EUROCONTROL is the current Network Manager nominated by the European Commission, and also includes an international operational ATC center in Maastricht, a research center in Bretigny sur Orge near Paris, and a training institute in Luxembourg. Among its many activities, EUROCONTROL is a founding member of SESAR and as such supports projects in the telecommunications domain, notably the Future Communications Infrastructure based on IP, multilink, as well as new and future data links such as LDACS, AeroMACS and Satellite Communications. EUROCONTROL has been contributing and working with the aviation community to what’s currently known as LDACS from the very beginning of Technology Investigations Description of L-Band Datalink system called AMACS (Allpurpose Multi-channel Aviation Communication System) and B-AMC (Broadband - Aeronautical Multi-Carrier Communication). EUROCONTROL continues to work together with the community to progress LDACS standardisation activities at the level of ICAO and appropriately addressing civil-military aspects with systems sharing the L-band. This technology is taking benefit of the latest industrial research that has integrated Secured Communication, Surveillance and Navigation capabilities.


Deutsche Flugsicherung GmbH

DFS Deutsche Flugsicherung GmbH, the German air navigation service provider, is a State-owned company under private law with 5,600 employees (as at 31 December 2019). DFS ensures the safe and punctual flow of air traffic over Germany. Around 2,200 air traffic controllers guide up to 10,000 flights in German airspace every day, more than three million movements every year. This makes Germany the country with the highest traffic volume in Europe. The company operates control centres in Langen, Bremen, Karlsruhe and Munich as well as control towers at the 16 designated international airports in Germany. Its subsidiary DFS Aviation Services offers products and services related to air traffic management worldwide and provides air navigation services at nine German regional airports as well as at London Gatwick Airport and Edinburgh Airport in the UK. DFS has been working on the integration of drones into air traffic since 2016 and has set up a joint venture, Droniq GmbH, with Deutsche Telekom.


German Aerospace Center (DLR)

DLR is the national aeronautics and space research center of the Federal Republic of Germany. Its extensive research and development work in aeronautics, space, energy, transport and security is integrated into national and international cooperative ventures. In addition to its own research, as Germany’s space agency, DLR has been given responsibility by the federal government for the planning and implementation of the German space program. DLR is also the umbrella organization for the nation’s largest project execution organization.

DLR has approximately 8000 employees at 16 locations in Germany: Cologne (headquarters), Augsburg, Berlin, Bonn, Braunschweig, Bremen, Goettingen, Hamburg, Juelich, Lampoldshausen, Neustrelitz, Oberpfaffenhofen, Stade, Stuttgart, Trauen, and Weilheim. DLR also has offices in Brussels, Paris, Tokyo and Washington D.C.

In the research area aeronautical communications the institute contributes to the standardization processes within ICAO (International Civil Aviation Organization) for future digital air traffic control/management communications systems. Moreover, concepts are developed for next generation aeronautical communications. The newly developed aeronautical communications concepts are validated by simulations and implemented in demonstrator hardware for validation through field trials.

In the context of LDACS, researchers from the DLR contributed significantly to the design and the specification of the physical layer.

Frequentis with headquarters in Vienna, Austria, has been active for more than 50 years in the development and delivery of products for Air Traffic Control (ATC) and the broader aeronautical market. The activities cover self-financed R&D and marketing of systems and products for this specific market.

Frequentis core activities lay in aeronautical communication systems, in particular voice communication systems. The company expertise covers both technological and operational aspects of the whole tactical aeronautical communications chain (voice switch, airborne and ground radio technologies, supporting functions).

Frequentis was the first company that introduced networked ground radio communication infrastructure (Austrocontrol 2002). Frequentis expects and is well prepared for more and more sophisticated requirements upon the ground infrastructure that will emerge as new types of VHF communications system get introduced.

Paris Lodron University of Salzburg

The department of Computer Sciences is a branch of the Faculty of Science of the Paris Lodron University of Salzburg. The Aeronautical Digital Communications group of the department has an ongoing tradition of research in the areas of air traffic simulation and wireless communication network design.

University of Salzburg’s sophisticated simulation tools have been used in a great number of national and international projects and helped to evaluate existing systems and design new ones. The research group was able to establish its expertise in range of relevant topics within the field of aerospace research.

In the context of LDACS, researchers from the University of Salzburg contributed significantly to the overall protocol design and the specification of the data-link layer.

Rohde & Schwarz

For 80 years, Rohde & Schwarz stands for quality, precision and innovation in all fields of wireless communications. The electronics group, headquartered in Munich (Germany), is among the world market leaders in all of its business fields. Rohde & Schwarz is the world’s leading manufacturer of wireless communications and EMC test and measurement equipment, as well as of broadcasting and T&M equipment for digital terrestrial television.

As an independent, family-owned company, Rohde & Schwarz generates its growth from its own resources. Since the company does not have to think in quarters, it can plan for the long term. As of June 30, 2013, the company had 9300 employees, with 5650 in Germany.

For several decades now, Rohde & Schwarz has supplied radiocommunications systems for a wide range of applications in the aviation sector – from air traffic control and airport communications to airline operational communications, radio test and measurement and the calibration of the equipment used.

For air traffic control agencies, airport operators, service providers and the armed forces, absolute system availability is paramount in flight operations. To meet this need, Rohde & Schwarz offers customers an optimized portfolio of solutions and services.

Equipped with the latest specialist knowledge and many years of experience, our engineers design and implement air traffic control communications systems that provide exceptional availability in live operations, even in the toughest environments.

Rohde & Schwarz has identified LDACS as the preferred candidate for the future L-band digital aeronautical communication system. In this context Rohde & Schwarz complements the current LDACS capabilities by modern security functions and applications. An LDACS demonstrator will show the enhanced capabilities to support future activities on the way to become the LDACS standard.
