Missions

KOREASAT-5

Payload

Built by Alcatel Alenia Space in Cannes, France, this new generation Spacebus 4000 C1 platform is fitted with the Avionique 4000 avionics system and accommodates 36 transponders in multi-band frequencies to meet its multi-mission objectives. A hybrid spacecraft designed for a 15-year service life, Koreasat 5 is owned jointly by the Agency for Defense Development of Korea and KT Corporation. It will be located in geostationary orbit at 113 degrees East Longitude as part of South Korea’s new high-capacity Spacecom System.

The Agency for Defense Development has managed the military side of the Koreasat 5 program and the Joint Chief of Staff of Korean Armed Forces will operate the SHF and Ka band transponders on the spacecraft to provide satellite communications services. Based in Daejon (about 120 miles south of Seoul), the Agency for Defense Development (ADD) was established in 1970 and is the sole national agency for R&D in defense technology. This agency contributes to enforcing national defense, improving the national R&D capacity and fostering domestic industry.

KT Corporation will operate 24 Ku band transponders. Half of these will be switched to regional beams to provide advanced broadband multimedia and digital television transmission services, as well as conventional telecom services to operators in the Asia-Pacific region. The remaining 12 Ku band transponders will replace Koreasat 2 capacity for domestic use in South Korea. Based in Seoul, KT Corporation (KT) was established in 1981 by the Korean Government and later privatized as a public corporation in 2002. The KT vision - The Value Networking Company - embodies a strong commitment to maximizing customer value and pursuing corporate growth by optimizing customized solution offerings.

In addition to building this state-of-the-art spacecraft, Alcatel Alenia Space, based in France, is also providing the ground control system to both KT and ADD, as well as Launch and Early Orbit Phase, and in-orbit tests. Alcatel Alenia Space is the European leader in satellite systems, at the forefront of orbit infrastructures. Created in July 2005, the company brings together the vast experience and know-how of Alcatel Space and Alenia Spazio to form a new leading force in European space technology. It represents a worldwide standard for space development, from navigation to telecommunications, from meteorology to environmental monitoring, from defense to science and observation.
