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 GE Astro Space (nyní Lockheed Martin Missiles and Space Co.), East Windsor, NJ (USA). Provozovatelem je firma GE American Communications, Inc. (Americom, nyní SES Americom, součást SES Global), Princeton, NJ (USA).
Tříose stabilizovaná družice typu Satcom. Nese převaděče pracující v pásmu C (6/4 GHz) s celkovou kapacitou 24 kanálů (1 televizní program nebo 1000 paralelních telefonních hovorů). Slouží pro zajišťování vnitrostátních telekomunikačních služeb v rámci USA včetně Aljašky, Havajských ostrovů a Portorika. Pro navedení na stacionární dráhu je vybavena vlastním motorem na TPL.
Plánovaný bod zavěšení je nad 83° z.d. Předpokládaná aktivní životnost je 8 roků.
Předchozí družicí této řady je RCA Satcom 3R (1981-114A), další jiného typu je RCA Satcom 5 (1982-105A).
