Die ESA arbeitet nun schon seit den 1970-er Jahren an der Satellitenkommunikation. Ihr Satellit OTS (Orbital Test Satellite) wurde bereits im Jahr 1980 f\u00fcr Videoverbindungen zwischen Gruppen in Deutschland und Gro\u00dfbritannien verwendet. Er leitete auch Nottelefonate weiter, nachdem ein Brand das bodengest\u00fctzte Telefonnetz in Lyon zerst\u00f6rt hatte.<\/p>\n<\/div>\n

Schon bald danach sorgte der Satellit Marecs f\u00fcr einen Durchbruch in der mobilen Telekommunikation. Wer von Schiffen aus mit Personen an Land telefonieren musste, konnte nun den unzuverl\u00e4ssigen Kurzwellenfunk durch Satellitentelefone ersetzen.<\/p>\n

W\u00e4hrend der sp\u00e4ten 1980-er und 1990-er Jahre wurden vier ECS-Satelliten im Weltraum stationiert. Jeder von ihnen konnte 12.000 Telefonverbindungen und 10 Fernsehkan\u00e4le quer durch Europa bew\u00e4ltigen.<\/p>\n

Der ESA-Satellit Olympus brachte 1989 wichtige Fortschritte in der direkten Fernseh\u00fcbertragung vom Satelliten zur Parabolantenne auf dem Dach des Teilnehmers. Au\u00dferdem hat \u00fcber Olympus die erste Daten\u00fcbertragung zwischen zwei Satelliten stattgefunden.<\/p>\n

\"Artemis\"

Die neuesten Entwicklungen sind einem Satelliten namens Artemis zu verdanken. Am 30. November 2001 wurde er f\u00fcr die erste Laserstrahl-Bild\u00fcbertragung aller Zeiten eingesetzt. Aus 832 km H\u00f6he \u00fcbertrug der Satellit SPOT 4 perfekte Bilder an Artemis, der 31.000 km \u00fcber der Erde kreiste.<\/p>\n

Heute sendet Artemis Bilder und riesige Datenmengen von Envisat an das ESA-Zentrum in der N\u00e4he von Rom.<\/p>","protected":false},"excerpt":{"rendered":"
