T\u00e4nu sidesatelliitidele saab spordi\u00fcritusi, intervjuusid, k\u00f5nesid ja s\u00f5du vaadata mugavalt tugitoolist.<\/p>\n<\/div>\n<p>Esimesed katsed, mille k\u00e4igus prooviti raadiosignaale kosmoses asuvatelt suurtelt \u00f5hupallidelt tagasi peegeldada, ei olnud eriti edukad. Neile j\u00e4rgnes 1962. aasta juulis satelliit nimega Telstar. See tekitas sensatsiooni, saates esimesed otse\u00fclekande telepildid Ameerikast Euroopasse. T\u00e4nap\u00e4eval on sadu sidesatelliite. Enamik neist kuulub eraettev\u00f5tetele. Need tiirlevad geostatsionaarsel orbiidil, 36 000 km k\u00f5rgusel ekvaatori kohal, et saaksid edastada signaali suurele alale.<\/p>\n<p>Televisiooni-, telefoni- ja raadiosignaale edastatakse satelliidile suure antenni abil. Satelliit v\u00f5imendab (tugevdab) neid ja saadab seej\u00e4rel edasi vastuv\u00f5tja jaama. Televisioonisignaale v\u00f5ib edastada ka otse majade katustel asuvatele antennidele.<\/p>\n<p>Side satelliidid on t\u00e4nap\u00e4eval v\u00e4ga suured ja v\u00f5imsad. Paljud neist lastakse orbiidile Euroopa Ariane-raketiga. 11. augustil 2005. aastal Ariane-5 abil orbiidile viidud satelliit Thaicom 4 kaalus 6,5 tonni. See oli suurim kunagi orbiidile viidud eraomanduses olev side satelliit.<\/p>","protected":false},"excerpt":{"rendered":"<p>Today, we are used to watching live TV from the other side of the world.
