Ariane 5's second liftoff this year


Ariane 5 liftoff
 
5 May 2017
Ariane 5 has delivered two telecom satellites, SGDC and Koreasat-7, into their planned orbits.

Arianespace announced the liftoff at 21:50 GMT (23:50 CEST, 18:50 local time) yesterday from Europe's Spaceport in Kourou, French Guiana. The mission lasted about 36 minutes.

Спойлер

Brazil's SGDC Geostationary Satellite for Communications and Defense, with a launch mass of 5735 kg, was the first to be released after about 28 minutes. The 3680 kg Koreasat-7 was released eight minutes later.

SGDC, operated by Telebras SA, will provide Brazil with broadband, new space technologies and strategic communications. The satellite has a design life of more than 18 years.

Koreasat-7, operated by ktsat, will provide telecommunications and broadcasting services over Korea, the Philippines, Indochina, India and Indonesia. The satellite has a design life of more than 15 years.

The payload mass for this launch was 10 289 kg. The satellites totalled about 9415 kg, with payload adapters and carrying structures making up the rest.

Flight VA236 was the 92nd Ariane 5 mission.

Two Thales Alenia Space satellites in orbit

| 05.05.2017 |

SGDC and KOREASAT-7 satellites successfully launched

Cannes, May 5th, 2017 – The SGDC and KOREASAT-7 telecommunications satellites, built by Thales Alenia Space for Brazil and South Korea respectively, were successfully orbited today by Arianespace in a dual launch using an Ariane 5 heavy launcher.

Спойлер

SGDC is a dual (civil-military) satellite for the customer Visiona, a joint venture of aircraft manufacturer Embraer and Brazil's telecommunications operator, Telebras. It will provide sovereign and safe means for the strategic communications of the government and the defense  and reduce the digital divide in Brazil by giving internet access to the whole country. This program reflects the close collaboration between Thales Alenia Space and Brazil, which includes the training of 30 Brazilian engineers in space industry techniques as well as the integration aboard the satellite of a structure panel made by the Brazilian company CENIC.



KOREASAT-7 was launched for the South Korean telecom/media service provider  KT Sat. The satellite will provide Internet access, multimedia, broadcasting and fixed communications services for South Korea, Philippines, Indonesia and India. The KOREASAT-5A satellite is now being integrated by Thales Alenia Space and will later join KTSAT's  fleet.

"This dual launch reflects the excellent teamwork between Thales Alenia Space and our customers Visiona and KT SAT," said Bertrand Maureau, Vice President, Telecommunications Business Line at Thales Alenia Space. "It also shows our ability to concurrently carry out launch campaigns for different customers, along with our wealth of services, the broad range of our telecom satellites, and our global business profile."

Telespazio, a joint venture between Leonardo (67%) and Thales (33%), supported Thales Alenia Space throughout the installation, configuration and set-up of the SGDC 13-meters antennas for TT&C (Telemetry, Tracking and Control) activities and to provide the equipment of both SGDC control centres in Brasilia (main) and Rio de Janeiro (backup). Telespazio's Fucino Space Centre, in co-operation with the Thales Alenia Space teams in Cannes, will manage the activities to put both satellites, SGDC and KOREASAT-7, into orbit.
