ESA activeaz\u0103 \u00een domeniul comunica\u021biilor prin satelit \u00eenc\u0103 din anii \u201970. \u00cenc\u0103 din 1980, satelitul s\u0103u de testare orbital\u0103 (Orbital Test Satellite) era utilizat pentru leg\u0103turi video \u00eentre grupuri din Germania \u0219i Marea Britanie. De asemenea, acesta a transmis apeluri telefonice de urgen\u021b\u0103 dup\u0103 ce un incendiu a distrus sistemul de la sol din Lyon.<\/p>\n<\/div>\n

La scurt timp dup\u0103 aceea, un satelit numit Marecs a adus o inovare revolu\u021bionar\u0103 \u00een domeniul telecomunica\u021biilor mobile. \u00cen loc s\u0103 foloseasc\u0103 radioul pe unde scurte, care era nesigur, oamenii puteau folosi telefoane prin satelit pentru a apela de pe nav\u0103 c\u0103tre \u021b\u0103rm.<\/p>\n

La sf\u00e2r\u0219itul anilor 1980 \u0219i \u00een anii 1990, au fost lansa\u021bi patru sateli\u021bi ECS. Fiecare dintre ace\u0219tia putea gestiona 12.000 de leg\u0103turi telefonice \u0219i 10 canale TV pe \u00eentreg teritoriul Europei.<\/p>\n

Progresele \u00een domeniul transmisiilor directe prin satelit c\u0103tre antenele parabolice de pe acoperi\u0219uri au fost marcate de lansarea satelitului Olympus al ESA \u00een 1989. Satelitul Olympus a fost utilizat \u0219i pentru primul transfer de date \u00eentre doi sateli\u021bi.<\/p>\n

\"Artemis\"

Cele mai recente progrese au fost realizate cu ajutorul unui satelit numit Artemis. La 30 noiembrie 2001, acesta a fost utilizat pentru prima transmisie de imagini realizat\u0103 vreodat\u0103 cu ajutorul unui fascicul laser. Imagini de o calitate impecabil\u0103 au fost transmise de la satelitul SPOT 4, care orbita la o altitudine de 832 km, c\u0103tre Artemis, aflat la 31 000 km deasupra P\u0103m\u00e2ntului.<\/p>\n

\u00cen prezent, satelitul Artemis este utilizat pentru a transmite imagini \u0219i cantit\u0103\u021bi uria\u0219e de date de la Envisat c\u0103tre centrul ESA din apropierea Romei.<\/p>","protected":false},"excerpt":{"rendered":"
