Ast\u0103zi, ne-am obi\u0219nuit s\u0103 urm\u0103rim emisiuni TV \u00een direct de la cel\u0103lalt cap\u0103t al lumii. Evenimentele sportive, interviurile, discursurile \u0219i r\u0103zboaiele pot fi urm\u0103rite din confortul fotoliului, gra\u021bie sateli\u021bilor de comunica\u021bii.<\/p>\n<\/div>\n

Primele experimente de reflexie a semnalelor radio de pe baloane de mari dimensiuni aflate \u00een spa\u021biu nu au avut prea mult succes. Acestea au fost urmate, \u00een iulie 1962, de un satelit numit Telstar. Acesta a f\u0103cut senza\u021bie prin transmiterea primelor imagini TV \u00een direct din America c\u0103tre Europa. Ast\u0103zi, exist\u0103 sute de sateli\u021bi de comunica\u021bii. Majoritatea sunt de\u021binu\u021bi de companii private. Ace\u0219tia se afl\u0103 pe orbite geosta\u021bionare, la 36 000 km deasupra ecuatorului, astfel \u00eenc\u00e2t s\u0103 poat\u0103 transmite semnalul pe o suprafa\u021b\u0103 extins\u0103.<\/p>\n

Semnalele TV, telefonice \u0219i radio sunt transmise c\u0103tre satelit printr-o anten\u0103 parabolic\u0103 de mari dimensiuni. Acestea sunt amplificate (\u00eent\u0103rite) de satelit, apoi transmise c\u0103tre o sta\u021bie de recep\u021bie. Semnalele TV pot fi, de asemenea, transmise direct c\u0103tre antenele parabolice amplasate pe acoperi\u0219urile caselor.<\/p>\n

Sateli\u021bii de comunica\u021bii sunt ast\u0103zi foarte mari \u0219i puternici. Mul\u021bi dintre ei sunt lansa\u021bi cu racheta european\u0103 Ariane. Satelitul Thaicom 4, lansat de Ariane-5 pe 11 august 2005, c\u00e2nt\u0103rea 6,5 tone. A fost cel mai mare satelit de comunica\u021bii de\u021binut de o companie privat\u0103 care a fost lansat vreodat\u0103.<\/p>","protected":false},"excerpt":{"rendered":"
