BSAT-1b 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 backup of BSAT-1a 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 twin BSAT-1a, by BSAT-3a. (en) BSAT-1bは放送衛星システムが所有するBSアナログ・デジタル放送用の予備衛星である。 1998年4月28日にアリアン4ロケットにより打ち上げられた。7月にヒューズ社からBSAT-1bを引き取り、8月1日よりBS放送用予備衛星として運用を開始した。 BSAT-1aと同様、106ワットの進行波管を使用し、Kuバンドのアクティブ・トランスポンダ4本と予備用ハイパワー・トランスポンダ4本を搭載し、BS-1、3、5、7、9、11、13、15chから4つを選択可能。設計寿命は10年。 2011年8月30日に運用を終了した。 (ja) O BSAT-1b 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.
