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 Ford Aerospace (USA). Provozovatelem je mezinárodní organizace International Telecommunication Satellite Organization (ITSO, nyní Intelsat, Ltd.), Washington, DC (USA).

Tříose stabilizovaná družice tvaru hranolu s výklopnými panely slunečních baterií, dodávajícími na konci života min. 1.2 kW. Nese 21 převaděč pracující v pásmu C (6/4 GHz) a 4 pracující v pásmu K_u (14/11 GHz), což představuje kapacitu 12 000 dvoucestných telefonních okruhů a 2 televizních kanálů. Jednotlivé frekvence jsou násobně využívány díky použití různých polarizací a prostorovému rozdělení svazků při použití úzce směrovaných parabolických antén. Televizní signál může být na družice vysílán i z malých transportovatelných terminálů. Pro navedení na stacionární dráhu slouží motor Thiokol Star 37XF na TPL.

Plánovaný bod zavěšení je nad ### 1 ### Předpokládaná aktivní životnost je 7 roků.

Předchozí družicí této řady je Intelsat 501 (1981-050A), další je Intelsat 504 (1982-017A).

Průběh letu

Datum	Událost
