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 pro přímé televizní vysílání. Postavila ji firma Hughes Space and Communications Co. (HSC, nyní Boeing Satellite Systems), Seal Beach, CA (USA) v závodech v El Segundo, CA (USA). Provozovatelem do r. 1992 byla firma British Satellite Broadcasting (BSB), London (Velká Británie), poté Telenor Satellite Services A/S, Oslo (Norsko).
Družice typu HS-376 nese čtyři převáděče pro přímé televizní vysílání, pracující v pásmu Ku (11-12 GHz).
Plánovaný bod zavěšení je nad 31° z.d.
