Dnes jsme zvykl\u00ed sledovat \u017eiv\u00e9 televizn\u00ed p\u0159enosy z druh\u00e9ho konce sv\u011bta. Sportovn\u00ed ud\u00e1losti, rozhovory, projevy i v\u00e1lky m\u016f\u017eeme sledovat z pohodl\u00ed k\u0159esla d\u00edky komunika\u010dn\u00edm satelit\u016fm.<\/p>\n<\/div>\n

Prvn\u00ed pokusy o odraz r\u00e1diov\u00fdch sign\u00e1l\u016f od velk\u00fdch bal\u00f3n\u016f ve vesm\u00edru nebyly p\u0159\u00edli\u0161 \u00fasp\u011b\u0161n\u00e9. V \u010dervenci 1962 na n\u011b nav\u00e1zala dru\u017eice s n\u00e1zvem Telstar. Ta vyvolala senzaci, kdy\u017e vyslala prvn\u00ed \u017eiv\u00e9 televizn\u00ed z\u00e1b\u011bry z Ameriky do Evropy. Dnes existuj\u00ed stovky komunika\u010dn\u00edch satelit\u016f. V\u011bt\u0161inu z nich vlastn\u00ed soukrom\u00e9 spole\u010dnosti. Ob\u00edhaj\u00ed na geostacion\u00e1rn\u00edch drah\u00e1ch ve v\u00fd\u0161ce 36 000 km nad rovn\u00edkem, aby mohly vys\u00edlat na velkou plochu.<\/p>\n

Televizn\u00ed, telefonn\u00ed a rozhlasov\u00e9 sign\u00e1ly jsou vys\u00edl\u00e1ny k satelitu pomoc\u00ed velk\u00e9 paraboly. Satelit je zesiluje a pot\u00e9 je odes\u00edl\u00e1 do p\u0159ij\u00edmac\u00ed stanice. Televizn\u00ed sign\u00e1ly mohou b\u00fdt tak\u00e9 vys\u00edl\u00e1ny p\u0159\u00edmo do parabol na st\u0159ech\u00e1ch dom\u016f.<\/p>\n

Komunika\u010dn\u00ed satelity jsou dnes velmi velk\u00e9 a v\u00fdkonn\u00e9. Mnoh\u00e9 z nich vyn\u00e1\u0161\u00ed do vesm\u00edru evropsk\u00e1 raketa Ariane. Satelit Thaicom 4, kter\u00fd byl 11. srpna 2005 vynesen raketou Ariane-5, v\u00e1\u017eil 6,5 tuny. Jednalo se o nejv\u011bt\u0161\u00ed soukrom\u00fd komunika\u010dn\u00ed satelit, jak\u00fd byl kdy vypu\u0161t\u011bn.<\/p>","protected":false},"excerpt":{"rendered":"
