Euroopa Kosmoseoperatsioonide Keskus (ESOC) on \u00fchendatud \u00fclemaailmse maapealsete jaamade v\u00f5rgustikuga.<\/p>\n<\/div>\n

P\u00e4rast orbiidile viimist saadetakse satelliidilt saadud andmed nendesse maapealsetesse jaamadesse ja sealt edasi ESOC-i. Seda teavet kasutatakse orbiidi arvutamiseks ja satelliidi t\u00f6\u00f6korra kontrollimiseks 24 tundi \u00f6\u00f6p\u00e4evas, seitse p\u00e4eva n\u00e4dalas.<\/p>\n

V\u00f5rgustikku kuulub mitu suurt jaama Euroopas ja Austraalias, sealhulgas Kiruna Rootsis, Redu Belgias ning Villafranca ja Cebreros Hispaanias.<\/p>\n

M\u00f5ned v\u00e4iksemad jaamad on ehitatud ka mujal maailmas, sealhulgas Kourous, mis on Euroopa kosmosesadam L\u00f5una-Ameerikas, ning Portugali Santa Maria saarel. Neid kasutatakse peamiselt missiooni k\u00e4ivitamise ja varajaste etappide ajal.<\/p>\n

2003. aastal ehitati Austraalias Perthi l\u00e4hedal New Norcias uus 35-meetrine antenn. See 120 tonni kaaluv hiiglaslik paraboolantenn on m\u00f5eldud sidepidamiseks kaugkosmosemissioonidega, nagu Rosetta ja Mars Express. Selle pind on \u00e4\u00e4rmiselt sile, ilma \u00fchegi \u00fcle 0,3 mm k\u00f5rguse ebatasasuseta. 2005. aastal ehitati sarnane antenn Cebrerosesse Hispaanias ning 2012. aastal lisandub v\u00f5rgustikku uus antenn Malarg\u00fces Argentinas.<\/p>\n

Maajaamad on konstrueeritud t\u00f6\u00f6tama erinevatel raadiosagedustel, mis sarnanevad mobiiltelefonides kasutatavatele. Need on nii tundlikud, et suudavad vastu v\u00f5tta signaale, mille v\u00f5imsus on sama suur kui tavalisel lambipirnil ja mis p\u00e4rinevad miljonite kilomeetrite kaugusel asuvast kosmoselaevast.<\/p>","protected":false},"excerpt":{"rendered":"
