Arianespace has successfully launched two telecommunications satellites: SGDC for Visiona Tecnologia Espacial S.A, on behalf of the Brazilian operator Telebras S.A. and the Brazilian government; and KOREASAT-7 for South Korean operator ktsat. The launch took place on Tuesday, May 4 at 6:50 pm (local time) from the Guiana Space Center, Europe’s Spaceport in Kourou, French Guiana. Today’s launch was the fourth of the year for Arianespace and the second in 2017 with the Ariane 5 heavy launcher, which also recorded its 78th successful mission in a row. In addition, it was the seventh Arianespace mission that carried two satellites built by Thales Alenia Space.

Arianespace, a major player in Brazil for 30 years, launches the country’s first governmental telecommunications satellite

SGDC, the Geostationary Defence and Strategic Communications Satellite, is the first satellite for the Brazilian operator Telebras S.A. to be orbited by Arianespace, within the scope of a turnkey contract with the company Visiona Tecnologia Espacial S.A. SGDC is a Brazilian government program, designed to meet three main objectives:

  • Reduce the country’s digital divide by supplying high-quality internet services across all of Brazil, within the scope of a national broadband plan.

  • Provide independent and secure strategic communications services for the Brazilian armed forces and government.

  • Provide the Brazilian space industry with key technologies so that it can play a growing role in the country’s future space programs.

A major player in Brazil since 1985, Arianespace has successfully launched all 11 Brazilian telecom satellites for legacy operator Embratel, as well as Star One, a wholly-owned Embratel subsidiary. With this latest mission, Arianespace has now launched three satellites providing coverage of Brazil during the past six months:

  • Star One D1 (December 2016)

  • SKY Brasil 1 (February 2017)

  • SGDC (March 2017)

Arianespace: a launch for ktsat and benchmark partner to the South Korean space program

KOREASAT-7 is the third satellite to be launched by Arianespace for South Korean operator ktsat, a subsidiary of KT Corp, the largest telecommunications/media service provider in the country. It follows the launches of KOREASAT-3 in 1999 and KOREASAT-6 in 2010. KOREASAT-7 will provide a wide range of video and data transmission applications, including internet access, direct-to-home (DTH) TV broadcasting, government communications and connectivity to VSAT (Very Small Aperture Terminal) networks, to extend services to isolated areas. Starting with the launch of the first ever South Korean satellites – KITSAT-1A in 1992 and KITSAT-2 in 1993 – Arianespace has become a major partner to the country’s space program. Including this latest Flight VA236 mission, more than half of South Korea’s geostationary satellites have been launched by Arianespace. The company’s order book includes two more satellites for the Korean Aerospace Research Institute (KARI): GEO-KOMPSAT-2A, planned for 2018, and GEO-KOMPSAT-2B, planned for 2019. Arianespace has launched 6 satellites for South Korea since 1992:

  • KITSAT 1A (1992)

  • KITSAT 2 (1993)

  • KOREASAT-3 (1999)

  • COMS-1 (2010)

  • KOREASAT-6 (2010)

  • KOREASAT-7 (May 4, 2017)
