Význam hodnot: Epocha - Datum (rok, měsíc, den), pro něž platí uvedené údaje. λ - Zeměpisná délka subsatelitního bodu ve stupních (kladná je východní délka, záporná je západní délka). Δλ - Denní změna polohy vzhledem k zemskému povrchu (změna zeměpisné délky subsatelitního bodu) ve stupních za den (kladná východním směrem, záporná západním směrem). i - Sklon dráhy k rovníku ve stupních.
Stacionární telekomunikační družice. Postavila ji firma Spar Aerospace, Toronto, ON (Kanada) na základě licence firmy Hughes Space and Communications Co. (HSC, nyní Boeing Satellite Systems), Seal Beach, CA (USA). Provozovatelem je firma Embratel S.A., Rio de Janeiro, RJ (Brazílie).
Rotací stabilizovaná družice typu HS-376 válcového tvaru o průměru 2.16 m a celkové výšce při startu 2.74 m (na dráze 6.58 m) má boční stěny pokryté slunečními bateriemi dodávajícími 935 W na počátku života a dobíjejícími 2 NiCd akumulátorové baterie. Nese 24(+6) převaděčů pracujících v pásmu C (5.925-6.425/3.700-4.200 GHz, šířka pásma 24×36 MHz, výkon 24×10 W), schopných zabezpečit přenos 57 600 telefonních hovorů nebo 24 televizních pořadů. Je určena pro vnitrostátní spojení (telefon, dálnopis, přenos dat a distribuce televizního signálu) na území Brazílie. Parabolická anténa o průměru 1.8 m je umístěna na stabilizované protirotující plošině. Pro korekce dráhy a úpravy osy rotace slouží 4 motorky na hydrazin. Pro navedení na stacionární dráhu je vybavena motorem Thiokol Star 30 na TPL.
Plánovaný bod zavěšení je nad 70° z.d. Předpokládaná životnost je 8 roků.
Předchozí družicí této řady je Brasilsat 1 (1985-015B), následující jiného typu je Brasilsat B1 (1994-049A).
