Brazilsat 1 & 2

Brazilsat 1 & 2 provide telecommunications services to Brazil. Canada's Spar Aerospace was awarded a $125 million contract to build, under license, two satellites based on Hughes' HS-376 design (similar to Anik D). Brazilsat 1 & 2 were the first two elements of Brazil's national Sistema Barasilero de Telecommunicacoes por Satelite (SBTS) network.
