T\u00e4nap\u00e4eval peame enesestm\u00f5istetavaks, et saame vaadata otse\u00fclekandeid sellistest s\u00fcndmustest nagu jalgpalli maailmameistriv\u00f5istlused v\u00f5i ol\u00fcmpiam\u00e4ngud. Need pildid on sageli j\u00f5udnud teie ekraanile maailma teiselt poolt.<\/p>\n<\/div>\n

Selle teeb v\u00f5imalikuks geostatsionaarsel orbiidil asuv side-satelliitide ring. Need satelliidid, mis tiirlevad umbes 36 000 km k\u00f5rgusel ekvaatori kohal, paistavad justkui h\u00f5ljuvat Maa pinna sama osa kohal. Nad v\u00f5tavad vastu maapinnal asuvatelt antennidelt telesisignaale ja v\u00f5imendavad neid. Seej\u00e4rel edastab satelliit pildi ja heli tagasi vaatajatele.<\/p>\n

Satelliittelevisiooni t\u00e4nap\u00e4evane ajastu algas 1962. aasta juulis, kui Telstar 1 edastas esimesed otse\u00fclekanded Ameerika \u00dchendriikidest Suurbritanniasse. 1965. aastal sai Early Bird esimeseks satelliidiks, mida kasutati regulaarseks telesaadete edastamiseks P\u00f5hja-Ameerika ja Euroopa vahel.<\/p>\n

Varem tuli telesisignaale saata spetsiaalsetesse maapealsetesse jaamadesse asuvatesse suurtesse paraboolantennidesse, enne kui need edastati kohalikele antennidele. T\u00e4nap\u00e4eval on satelliitsignaalid nii v\u00f5imsad, et neid suudavad vastu v\u00f5tta ka v\u00e4ikesed paraboolantennid kontorite ja elamute katustel. Selline otse koju edastatav digitaaltelevisioon on paljudes riikides muutunud v\u00e4ga populaarseks.<\/p>\n

Reaalajas satelliitsidet on v\u00f5imalik luua ka kaugete kontorite vahel v\u00f5i linna haiglate arstide ja kaugetes maapiirkondade k\u00fclades asuvate patsientide vahel. Satelliite kasutatakse ka digitaalsete raadiosaadete edastamiseks, mida saab vastu v\u00f5tta nii autodes kui ka kaasaskantavates raadiovastuv\u00f5tjates.<\/p>","protected":false},"excerpt":{"rendered":"
