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. Provozovatelem je firma Mobile Satellite Ventures (USA), později LightSquared Subsidiary LLC (USA).

Zajišťuje mobilní komunikace pro severoamerický kontinent (USA a Kanadu). Poskytované služby jsou kompatibilní se službami kanadské družice MSat-2 (1996-022A).

Plánovaný bod zavěšení je nad 101° z.d. Předpokládaná aktivní životnost je 15 roků.
