Sportsbegivenheder, interviews, taler og krige kan alle f\u00f8lges fra en behagelig l\u00e6nestol takket v\u00e6re kommunikationssatellitter.<\/p>\n<\/div>\n<p>De f\u00f8rste fors\u00f8g p\u00e5 at reflektere radiosignaler fra store balloner i rummet var ikke s\u00e6rlig vellykkede. I juli 1962 fulgte en satellit ved navn Telstar. Den vakte stor opsigt ved at sende de f\u00f8rste direkte tv-billeder fra Amerika til Europa. I dag findes der hundredvis af kommunikationssatellitter. De fleste af dem ejes af private virksomheder. De kredser i geostation\u00e6re baner, 36 000 km over \u00e6kvator, s\u00e5 de kan sende til et stort omr\u00e5de.<\/p>\n<p>TV-, telefon- og radiosignaler sendes op til satellitten via en stor parabol. De forst\u00e6rkes af satellitten og sendes derefter videre til en modtagestation. TV-signaler kan ogs\u00e5 sendes direkte til paraboler p\u00e5 hustagene.<\/p>\n<p>Kommunikationssatellitter er i dag meget store og kraftfulde. Mange af dem opsendes med den europ\u00e6iske Ariane-raket. Thaicom 4-satellitten, der blev opsendt med Ariane-5 den 11. august 2005, vejede 6,5 ton. Det var den st\u00f8rste privat ejede kommunikationssatellit, der nogensinde er blevet opsendt.<\/p>","protected":false},"excerpt":{"rendered":"<p>Today, we are used to watching live TV from the other side of the world.
