Thales Alenia Space Wins Korean Order for Four EO Satellites

Thales Alenia Space Will Support Korean Aerospace Industry for the Development of a Constellation of Earth Observation Radar Satellites

SEOUL --- Thales Alenia Space, a joint venture between Thales (67%) and Leonardo (33%), today announced that it has signed two contracts with Korea, one with Aerospace Industries, LTD. (KAI) and one with Hanwha Systems Corporation (HSC), to develop a constellation of high-resolution observation radar satellites for the Agency for Defence Development (ADD), known as Korea “425 Project”, to serve South Korea.

Korean Aerospace Industries leads a consortium including South Korea’s Hanwha System and Thales Alenia Space. All three companies have been involved in developing satellites and related technologies for a number of years. Technical cooperation and several know-hows required for the SAR (Synthetic Aperture Radar) Satellites development will be transferred to Korean companies, up to a maximum involvement in the production of the last satellite of the Constellation, providing them with an outstanding growth in the field of design and development of Earth Observation Systems.

For the four satellites, Thales Alenia Space will provide the SAR Payloads and the platform elements (especially for Control Momentum Gyro and sensors) derived from the HE-R1000 product (High Efficiency Radar), part of the Thales Alenia Space Observation product family that includes both radar and optical satellites. This technology will enable short revisit times for each of the satellites, and support all-weather operation, with a very high global revisit frequency. The constellation will be used by the Korean authorities for surveillance, intelligence and control of specific areas of interest thanks to the acquisition of high-resolution images.

Agility is one of the primary assets for advanced missions entrusted to this new generation of high-resolution surveillance satellites. Based on an active feed array and reflector antenna innovative solution, the satellites ensure superior quality images, while unique agility capability is provided thanks to the adaptation of a control momentum gyro: a spinning rotor and one motorized gimbal tilt the rotor’s angular momentum. As the rotor tilts, the changing angular momentum causes a gyroscopic torque that rotates the spacecraft. Moving around the three axes, these “dancing satellites”, will be fitted with a special antenna developed within the scope of the Thales Alenia Space Reseach & Development program. With a diameter of 5 meters, the new-generation antenna will open its 24 petals once in space.

“Thales Alenia Space is honored to have earned the confidence of the Korean Ministry of Defence and other authorities involved in this project, who recognized our proven track record in delivering state-of-the-art observation satellites,” said Donato Amoroso, Senior Vice-President, Observation, Exploration and Navigation at Thales Alenia Space. “The contract signed today is a superb opportunity for cooperation between Italy and Korea. It confirms the new global trend in the space business and the ‘new space’ transformation strategy being implemented by Thales Alenia Space, with the ultimate aim of becoming a major manufacturer of small satellite constellations featuring short revisit times.

“This business win confirms Thales Alenia Space’s long-standing expertise and

unique global position in the design, development and construction of radar Earth observation satellites, as well as the development of satellite constellations. It is also based on the heritage of the excellent performance of the COSMO-SkyMed program, the world’s most advanced spaceborne radar system.”

Thales Alenia Space’s participation in the 425 Project is the latest milestone in its long-standing collaboration with South Korea on a number of space programs, including KOMPSAT-5, the Koreasat telecommunications satellite family, GEO-KOMPSAT-2, KASS, etc.

COSMO-SkyMed, funded by the Italian space agency ASI, the Italian Ministry of Defence and the Italian Ministry of Education, Universities and Scientific Research, is the first “dual use” Earth observation system, spanning both civil and military applications. Its four identical satellites “watch” our planet from space day and night under all atmospheric conditions, using high resolution X-band radars. Thales Alenia Space is the program prime contractor, responsible for the entire system, including the ground and space segments, and leading a consortium of companies from throughout the space industry. Telespazio developed the ground segment and hosts the Constellation Control Center at the Fucino Space Center. e-GEOS (ASI/Telespazio) is the world-wide exclusive distributor of COSMO-SkyMed data.

Thales Alenia Space is currently involved in the development of the COSMO Second Generation (CSG) constellation, which represents a major generational leap in terms of technology, performance and operational life. It will provide new application possibilities, in particular for risk management and damage assessment of natural and man-made disasters. CSG Earth observation spacecraft feature state-of-the-art technologies and engineering solutions, further bolstering Italian leadership in this sector.

This second-generation system, including its ground segment, will set a new performance standard for space-based radar observation systems in terms of precision, image quality and the flexibility of user services. Satellites and instruments designed and developed by Thales Alenia Space, including Meteosat Third Generation (MTG) weather satellites and the COSMO-SkyMed radar constellation, have already made a pivotal contribution to damage assessment following natural disasters, such as earthquakes, landslides and flooding, the monitoring of critical infrastructures, tracking the movement of glaciers, and monitoring illegal activities such as oil spills and the trafficking of goods or people.

Thales Alenia Space delivers cost-effective solutions for telecommunications, navigation, Earth observation, environmental management, exploration, science and orbital infrastructures. A joint venture between Thales (67%) and Leonardo (33%), Thales Alenia Space also teams up with Telespazio to form the parent companies’ Space Alliance, which offers a complete range of services. Thales Alenia Space posted consolidated revenues of 2.6 billion euros in 2017 and has 7,980 employees in nine countries.
