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.

Popis objektu

Stacionární telekomunikační družice. Postavila ji firma General Electric Co. (GE), St. Louis, MO (USA). Provozovatelem je GTE Spacenet Corp. (USA).

Družice určená pro vnitrostátní telefonní spojení, přenos dat a retranslaci televizních programů nese 16 převaděčů pracujících v pásmu Ku.

Plánovaný bod zavěšení je nad 125° z.d. Předpokládaná aktivní životnost je 13 let.

Předchozí družicí tohoto typu je GStar 3 (1988-081A).
