BSAT-1a was a geostationary communications satellite designed and manufactured by Hughes (now Boeing) on the HS-376 platform. It was originally ordered and operated by the Broadcasting Satellite System Corporation (B-SAT). It was used as the main satellite to broadcast television channels for NHK and WOWOW over Japan. It had a pure Ku band payload and operated on the 110°E longitude until it was replaced, along its backup BSAT-1b, by BSAT-3a. On 3 August 2010, it was decommissioned and placed on a graveyard orbit.

(en) BSAT-1aは、かつて放送衛星システムが所有していた、BS放送用の衛星である。これ以降の放送衛星システム所有の放送用衛星シリーズは同社の略称からB-SATシリーズと呼ばれる。 (ja) O BSAT-1a foi um satélite de comunicação geoestacionário japonês construído pela Hughes que esteve localizado na posição orbital de 110 graus de longitude leste e era operado pela Broadcasting Satellite System Corporation. O satélite foi baseado na plataforma HS-376 e sua vida útil estimada era de 10 anos. O mesmo ficou fora de serviço em julho de 2010 e foi movido para a órbita cemitério. (pt) BSAT-1a，為日本一枚已退役的广播卫星，於1997年發射，由該國各公、私營電視台合營的「廣播衛星系統公司」持有。於服役期間，此衛星定位於東經110°E，並主要負責透過Ku波段，轉播日本放送協會及WOWOW的衛星電視頻道。與備份星BSAT-1b不同，此衛星一直專責轉播模擬衛星電視訊號。隨著同一公司的BSAT-3a於2007年發射升空，並接替此衛星的工作，BSAT-1a已於2010年退役。 (zh)
