Europa ser med stor tillid frem til at f\u00e5 verdens f\u00f8rste ikke-milit\u00e6re satellitnavigationssystem, nu hvor de f\u00f8rste fire Galileo-satellitter har best\u00e5et deres test med glans.<\/p>\n<\/div>\n

Galileo-kvartetten blev opsendt i 2011 og 2012 for at bevise, at det komplekse system fungerede som lovet. Grunden til, at man opsendte fire satellitter, er, at det er det mindste antal satellitter, der er n\u00f8dvendigt for n\u00f8jagtigt at kunne lokalisere steder p\u00e5 Jorden. Siden da har man gennemf\u00f8rt en r\u00e6kke test for at p\u00e5vise, at systemet fungerer som planlagt.<\/p>\n

Den 12. marts 2013 gennemf\u00f8rte satellitterne deres f\u00f8rste historiske pr\u00e6cise lokalisering af et sted p\u00e5 jorden. I l\u00f8bet af de f\u00f8lgende m\u00e5neder blev der sendt mange flere navigationsmeddelelser som led i en intensiv test af hele Galileo-systemet.<\/p>\n

Alt dette h\u00e5rde arbejde har vist, at Galileo fungerer rigtig godt. Med blot fire satellitter har det v\u00e6ret i stand til at bestemme positioner med en n\u00f8jagtighed p\u00e5 8 m vandret og 9 m lodret. Dets gennemsnitlige tidsn\u00f8jagtighed er 10 milliarddele af et sekund, og de fleste n\u00f8dsignaler er hurtigt blevet lokaliseret med en n\u00f8jagtighed p\u00e5 2 km. Denne ydeevne vil blive endnu bedre, n\u00e5r det fulde Galileo-system tages i brug.<\/p>\n

Europa ser nu frem til at opsende de resterende satellitter og etablere yderligere jordstationer. Det er planen, at seks satellitter skal slutte sig til de eksisterende fire i l\u00f8bet af 2014, s\u00e5 Galileos operationelle tjenester kan g\u00e5 i gang inden \u00e5rets udgang!<\/p>","protected":false},"excerpt":{"rendered":"
