Thales Alenia Space is preparing to ship Brazil’s dual-use (civil/military) Geostationary Defence and Strategic Communications Satellite (SGDC) to the Kourou launch pad in French Guyana to be launched by an Ariane 5 in March.

Thales Alenia Space signed the SGDC contract with Visiona (a joint venture between Embraer and Telebras) at the end of 2013. The programme plays a key role in the Brazilian Space Agency’s Space (AEB) development plan, while also addressing the strategic requirements of the Ministry of Defence.

Based on the Spacebus 4000 platform, the SGDC satellite will carry two payloads, one with 50 Ka-band transponders offering throughput of up to 80 Gbps, and the other with seven X-band transponders. The satellite will weigh about 5.8t at liftoff, and will offer more than 11kW of power. It will be positioned in orbit at 75 degrees West.

The SGDC programme is an integral part of Brazil’s strategy to reinforce its independence and sovereignty. It is designed to meet two main objectives: the implementation of a secure satellite communications system for the Brazilian armed forces and government; and support for the deployment of the National Broadband Plan (PNBL), coordinated by Telebras as operator, which aims to reduce the digital divide in the country.

The Brazilian Space Agency and Thales Alenia Space also signed a Memorandum of Understanding (MoU) concerning technology transfer in support of the development of Brazil’s own space programme. As part of this effort, Thales Alenia Space has established a unit at the San José dos Campos technology park in Brazil, to work more closely with its local customers and partners.

The contract also includes a complete ground segment for satellite and mission control, along with orbital positioning, acceptance testing in orbit and operational support, preceded by a comprehensive training programme for Brazilian operators.

Le 3 février, les représentants de la presse ont été invités à voir le satellite de télécommunications brésilien SGDC dans les salles blanches de l’usine d’assemblage de Thales Alenia Space, à Cannes, avant son transfert vers la Guyane.

Le satellite SGDC (Geostationary Defense and Strategic Communications – satellite géostationnaire de défense et de communications sécurisées) est un satellite de télécommunications dual construit par Thales Alenia Space pour le Brésil.
Le contrat, estimé à plus de 400 M€, avait été passé en décembre 2013 avec l’opérateur Visiona, société commune entre Telebras et Embraer. Il s’inscrit à la fois au cœur du plan spatial de l’agence spatiale brésilienne AEB, et du plan stratégique du Ministère de la Défense brésilien.
Il comprend la construction du satellite SGDC, mais aussi la fourniture d’un système sol global, et d’un vaste programme de soutien transfert de technologies : installation d’une entité Thales Alenia Space Brazil dans le parc technologique de San José dos Campos, accueil de plus de 30 ingénieurs brésiliens à Toulouse et Cannes, contrats de sous-traitance avec plusieurs sociétés brésiliennes, et création d’une académie spatiale nationale.

Lancement le 21 mars.
Basé sur la plateforme Spacebus 4000 et doté d’une puissance de 9 kW, le satellite SGDC emportera 40 transpondeurs en bande Ka pour le Ministère des télécommunications, ainsi que 5 relais en bande X pour le Ministère de la Défence brésiliens. D’une masse de 5 754 kg, il sera placé au-dessus Brésil, à 75°W.
Son transfert entre l’usine d’assemblage de Cannes et Kourou est prévu pour le 13 février, pour un lancement le 21 mars prochain depuis le Centre spatial guyanais, à l’aide d’un lanceur Ariane 5 ECA d’Arianespace.
