Satellitkommunikation anv\u00e4nds numera i m\u00e5nga ovanliga projekt. Detta har blivit m\u00f6jligt tack vare kraftfullare satelliter och snabbare datal\u00e4nkar. Ett omr\u00e5de som st\u00f6ds av ESA \u00e4r utvecklingen av multimedia. I augusti 2004 sk\u00f6ts en satellit upp med AmerHis \u2018v\u00e4xel i rymden\u2019 ombord. Detta banade v\u00e4g f\u00f6r h\u00f6ghastighetsinternet, video och radio p\u00e5 beg\u00e4ran till en betydligt l\u00e4gre kostnad. Det har varit s\u00e5 framg\u00e5ngsrikt att en andra AmerHis-nyttolast sk\u00f6ts upp med satelliten Amazonas-2 \u00e5r 2009.<\/p>\n<\/div>\n

ESA st\u00f6der ocks\u00e5 anv\u00e4ndningen av satelliter f\u00f6r \u2018virtuellt\u2019 l\u00e4rande. Ett av de f\u00f6rsta projekten, som kallades Trapeze, gjorde det m\u00f6jligt f\u00f6r barn p\u00e5 tivoli och i cirkusar att se och prata med l\u00e4rare som befann sig l\u00e5ngt bort. Allt som beh\u00f6vdes var en b\u00e4rbar mottagarparabol och en dator.<\/p>\n

N\u00e4r det g\u00e4ller telemedicin kan hemv\u00e5rd tillhandah\u00e5llas via satellit. Med hj\u00e4lp av en videol\u00e4nk kan patienter i avl\u00e4gsna omr\u00e5den be om hj\u00e4lp och r\u00e5d fr\u00e5n l\u00e4kare.<\/p>\n

Ett ESA-st\u00f6tt projekt har ocks\u00e5 visat hur h\u00f6ghastighetskommunikation via satellit kan leverera musik i CD-kvalitet p\u00e5 beg\u00e4ran. Kunderna v\u00e4ljer fr\u00e5n en webbplats och tar emot sin musik via satellit. Musiken skickas sedan till deras datoranslutna stereoanl\u00e4ggning eller br\u00e4nns direkt p\u00e5 en CD.<\/p>\n

Systemet kan \u00e4ven anv\u00e4ndas f\u00f6r att distribuera programvara, b\u00f6cker, filmer eller andra digitala produkter.<\/p>","protected":false},"excerpt":{"rendered":"
