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

Vojenská stacionární telekomunikační družice.

Plánovaný bod zavěšení je nad 177° z.d.

Průběh letu

Datum	Událost
1990-01-09	12:35:00 UT: Vzlet na palubě raketoplánu Columbia (1990-002A).
1990-01-10	13.18 UT: Vypuštěn z nákladového prostoru raketoplánu Columbia (1990-002A) a stupněm PAM-D naveden na předběžnou přechodovou dráhu, z níž vlastním motorem později přešel na předběžnou stacionární dráhu.
1990-01-15	Zakotven nad 177° z.d. Krátce poté byly úspěšně vyklopeny anténní systémy a byly zahájeny prověrky systémů družice.
1997-10-17	Začala v omezeném rozsahu poskytovat služby též australskému válečnému námořnictvu.
1998-únor	Koncem měsíce vymanévrován2 z pozice nad 77° v.d.
1998-04-03	Zakotven2 nad 155° v.d.
1998-05-07	Na základě dohody mezi USA a Austrálií začala družice poskytovat služby australským ozbrojeným silám.
