Euroopa ootab kindlalt maailma esimese mittes\u00f5jalise satelliitnavigatsioonis\u00fcsteemi kasutuselev\u00f5ttu, n\u00fc\u00fcd, kui esimesed neli Galileo satelliiti l\u00e4bisid katsed suurep\u00e4raste tulemustega.<\/p>\n<\/div>\n

Galileo nelik lasti orbiidile aastatel 2011 ja 2012, et t\u00f5estada, et see keerukas s\u00fcsteem toimib nii, nagu lubatud. Nelja satelliidi orbiidile viimise p\u00f5hjuseks oli asjaolu, et see on minimaalne satelliitide arv, mis on vajalik Maa peal asukohtade t\u00e4pseks m\u00e4\u00e4ramiseks. Sellest ajast alates on s\u00fcsteem l\u00e4binud katsetuste perioodi, et t\u00f5estada, et s\u00fcsteem toimib plaanip\u00e4raselt.<\/p>\n

12. m\u00e4rtsil 2013 tegid satelliidid oma esimese ajaloolise maapinnal asuva asukoha t\u00e4pse m\u00e4\u00e4ramise. J\u00e4rgnevate kuude jooksul saadeti kogu Galileo-s\u00fcsteemi p\u00f5hjaliku kontrollimise k\u00e4igus veel palju navigatsioonis\u00f5numeid.<\/p>\n

K\u00f5ik see raske t\u00f6\u00f6 on t\u00f5estanud, et Galileo toimib v\u00e4ga h\u00e4sti. Vaid nelja satelliidiga on s\u00fcsteem suutnud m\u00e4\u00e4rata asukoha horisontaalselt 8 meetri ja vertikaalselt 9 meetri t\u00e4psusega. S\u00fcsteemi keskmine ajam\u00e4\u00e4ramise t\u00e4psus on 10 miljardiksekundit ning enamik h\u00e4daabik\u00f5nesid on suudetud kiiresti lokaliseerida 2 km t\u00e4psusega. Need tulemused paranevad veelgi, kui kogu Galileo s\u00fcsteem t\u00f6\u00f6le hakkab.<\/p>\n

Euroopa ootab n\u00fc\u00fcd p\u00f5nevusega \u00fclej\u00e4\u00e4nud satelliitide orbiidile viimist ja uute maapealsete jaamade paigaldamist. 2014. aasta jooksul on kavas lisada olemasolevatele neljale satelliidile veel kuus, nii et Galileo teenused saaksid alata juba aasta l\u00f5puks!<\/p>","protected":false},"excerpt":{"rendered":"
