Arianespace launches first Brazilian X-band satellite

08 May 2017

Brazil's military and civilian Geostationary Communications Satellite (Satélite Geoestacionário de Defesa e Comunicações: SGDC) was launched on 4 May.

SGDC was sent towards orbit on a 780-ton Ariane 5 ECA rocket built by Airbus Safran Launchers for Arianespace, and launched from Ariane Launch Complex No 3 at the Guiana Space Centre in Kourou, French Guiana. The mission was originally set for 21 March but was postponed due to local work stoppages.

The satellite will begin initial operations in about a month, and provide communication services in three months. It is the first Brazilian government X-band-capable satellite.

SGDC, based on a Thales Alenia Space (a joint venture of Thales and Leonardo) Spacebus 4000C4 platform, will provide X-band secure communication services for military, and Ka-band internet broadband access to state-owned Telebras to address the country's National Broadband Plan.
