Europa ser med stor optimisme frem til \u00e5 f\u00e5 verdens f\u00f8rste ikke-milit\u00e6re satellittnavigasjonssystem, n\u00e5 som de fire f\u00f8rste Galileo-satellittene har best\u00e5tt testene med glans.<\/p>\n<\/div>\n

Galileo-kvartetten ble skutt opp i 2011 og 2012 for \u00e5 bevise at det komplekse systemet fungerte som lovet. Grunnen til at de skj\u00f8t opp fire satellitter, er at dette er det minste antallet satellitter som trengs for \u00e5 lokalisere steder p\u00e5 jorden n\u00f8yaktig. Siden den gang har de gjennomg\u00e5tt en testperiode for \u00e5 demonstrere at systemet fungerer som planlagt.<\/p>\n

Den 12. mars 2013 gjennomf\u00f8rte satellittene sin f\u00f8rste historiske posisjonsbestemmelse av et sted p\u00e5 bakken. I l\u00f8pet av de p\u00e5f\u00f8lgende m\u00e5nedene ble det sendt ut mange flere navigasjonsmeldinger som ledd i en grundig test av hele Galileo-systemet.<\/p>\n

Alt dette harde arbeidet har vist at Galileo fungerer sv\u00e6rt godt. Med bare fire satellitter har det v\u00e6rt i stand til \u00e5 bestemme posisjoner med en n\u00f8yaktighet p\u00e5 8 m horisontalt og 9 m vertikalt. Den gjennomsnittlige tidsn\u00f8yaktigheten er 10 milliarddeler av et sekund, og de fleste n\u00f8dsignaler har raskt blitt lokalisert med en n\u00f8yaktighet p\u00e5 2 km. Ytelsen vil bli enda bedre n\u00e5r hele Galileo-systemet tas i bruk.<\/p>\n

Europa ser n\u00e5 frem til \u00e5 skyte opp de gjenv\u00e6rende satellittene og sette opp flere bakkestasjoner. Det er planlagt at seks satellitter skal slutte seg til de fire eksisterende i l\u00f8pet av 2014, slik at Galileos operative tjenester kan settes i gang innen utgangen av \u00e5ret!<\/p>","protected":false},"excerpt":{"rendered":"
