1985-015B
The SBTS 1 (Sistema Brasilero de Telecomunicacoes par Satelite) satellite was built by Spar and Hughes for Telebras (Telecomunicacoes Brasileiras), part of the Brazilian Ministry of Communications. Named Brasilsat 1 on reaching orbit, the HS376 satellite was operated by Embratel (Empresa Brasileira de Telecomunicacoes SA, Rio), the operational arm of Telebras.
In 1995 the satellite was leased by Hughes Communications Inc to provide supplemental C-band capacity for US domestic communications in the Galaxy system. In 2000 it was still in use by Panamsat; it was retired in 2002.
