Thales Alenia Space is European leader reference in telecoms, radar and optical Earth observation, defense and security, navigation and science and space infrastructures and transportation. Thales Alenia Space is a joint venture between Thales (67%) and Leonardo-Finmeccanica (33%) and has 9 industrial sites in 8 European countries (France, Italy, Spain, Belgium, Germany, England, Switzerland and Poland) with 7,500 employees worldwide.

Thales Alenia Space Italia employs around 2,200 people and has sites in Rome, Turin, L’Aquila and Milan.


Thales Alenia Space is at the heart of the most high-performance satellite technologies in both civil and defense sectors.



The company is deeply involved in:



  • Environmental projects based on Earth observation such as the Global Monitoring for Environment and Safety (Copernicus) program with Sentinel-1, Meteorology such as MSG (Thales Alenia Space provided all the Meteosat satellites for Eumetsat), Climatology as satellite prime contractor for SMOS (Soil Moisture and Ocean Salinity) mission;

  • Navigation with Galileo (as prime contractor of EGNOS - the precursor of Galileo);

  • Defense with major programs such as the French Syracuse (I, II and III) and the Italian (SICRAL) telecommunication satellites; and in observation programs such as Helios (France), COSMO-SkyMed (Italy) and SAR-Lupe (Germany);

  • Science and Exploration, as prime contractor for the ExoMars mission design - one of the most ambitious exploration missions, and for the GOCE satellite (Gravity Field and Steady-State Ocean Circulation Explorer); The Company is also involved in programmes such as Bepi Colombo and Euclid, that will explore dark energy and dark matter, the essential but still mysterious ingredients in today’s “Standard Model’ of cosmology.

  • Space Infrastructure and Transportation as provider of more than 50% of the ISS pressurized volume.



Today, Thales Alenia Space is the leading European supplier of satellite-based solutions for Defense and Security, with strong positions in both space and ground segments. In addition, the company is the European benchmark supplier of facility operational services for the European Space Agency (ESA), the French space agency CNES, the Italian Space Agency (ASI) as well as for the French, Italian and German Ministries of Defense, the Defense procurement agency DGA and other major customers. Thales Alenia Space is also active in the civil-military satellite export market, through Koreasat 5 an 7 in South Korea, Star One in Brazil and Yahsat in United Arab Emirates.


Thales Alenia Space is one of the world’s leading space telecom players, with orders from the United States, Russia, Latin America, Africa and the Middle East, and growing business with Asian customers.


Thales Alenia Space is also the worldwide leader in telecommunication payloads with over 200 payloads ordered (i.e. 30% of market share). In addition, we are among the world leaders in space borne microwave equipment, with products integrated in 50% of all satellites built worldwide. Thales Alenia Space is not only the world leader in geostationary weather satellites (as prime for first and second-generation Meteosat satellites - MSG), but has also developed strong expertise in low-orbit climatology missions (such as Calipso for CNES/NASA) and in the construction of Earth observation ground segments.


After its important participation in Cryosat and Envisat environmental monitoring satellite for the European Space Agency (ESA), in Earth observation satellites SPOT and in ocean observation satellites Jason 1 & 2 for CNES/NASA and SMOS (Soil Moisture and Ocean Salinity) program for ESA, Thales Alenia Space is also playing a major role in Kopernikus, a key European program that aims to set up a global monitoring system, with the provision of Sentinel-1 and Sentinel-3 satellites. Copernicus enables Thales Alenia Space to provide its competencies in meteorology, environment monitoring and earth observation.

Offering dual civil-military technologies, Thales Alenia Space is strongly involved in ORFEO (Optical and Radar Federated Earth Observation), the French-Italian dual-use system. In the scope of this program, the company has provided the dual COSMO-SkyMed radar satellites and its associated ground segment and the Pleïades optical satellites.


Thales Alenia Space was at the heart of the most ambitious and technological success of the Cassini-Huygens mission to Titan. Early in 2005, after a journey of seven years through our solar system, the Huygens space probe landed on the Saturn moon Titan and is now ending its operational life. In addition, Thales Alenia Space is involved in the ESA exploration challenges such as Rosetta, Mars Express, Venus Express, Herschel/Planck and ExoMars. The ExoMars program, worth 600 million euros, is one of the most important exploration missions. It aims at sending a lander rover to Mars in order to find traces of past or present life. Thales Alenia Space is prime contractor for ExoMars.


This position has been achieved thanks to a number of complementary skills, including the ability to coordinate international alliances in long-term endeavors, to assemble, integrate and test scientific probes, and through its proven expertise in the technologies needed for space astronomy and interplanetary missions with landings as well as in outer space telecommunications.


Thales Alenia Space defined the overall architecture of the Galileo system on behalf of the European Union and the satellite architecture for ESA. Thales Alenia Space has been a driving partner in Galileo since the outset, in charge of the ground segment as well as the satellite integration and providing critical equipment and subsystems (IOV phase). 


Thales Alenia Space has designed and built 50% of the Station’s pressurized volume, that is the living space. The company also contributed to the related launch, transportation and re-entry systems.


Thales Alenia Space is prime contractor for the three inhabitable Multipurpose Pressurized Logistics Modules (MPLM) - Leonardo/ Rafaello/ Donatello, Nodes 2 and 3 (the interconnecting elements between the various pressurized modules on the ISS), and the Cupola observation module; and is a main contributor to the Columbus scientific laboratory for research in a microgravity environment and to the Automated Transfer Vehicle (ATV).

Looking forward, Thales Alenia Space provided to ESA the Intermediate eXperimental Vehicule (IXV) system for atmospheric reentry and for the development of EXPERT program  (EXPErimental Re-entry Test-bed system) for re-entry technology demonstration) and to Orbital the pressurized cargo modules to re-supply the International Space Station  (PCMs).
