Den 12. oktober blev en Sojuz-raket affyret fra rumhavnen i Kourou i Fransk Guyana med to Galileo-rumfart\u00f8jer om bord. Den tredje og fjerde satellit i Europas globale navigationssatellitsystem sluttede sig til de to satellitter, der blev opsendt n\u00e6sten pr\u00e6cis et \u00e5r tidligere. Disse to nye satellitter fuldender \u2018testgruppen\u2019 for Galileo-programmet.<\/p>\n<\/div>\n

Den spektakul\u00e6re opsendelse af VS03-flyvningen fandt sted kl. 20:15 CEST. Alle rakettrin fungerede som planlagt, og det \u00f8verste trin udsendte satellitterne i deres bane i en h\u00f8jde p\u00e5 ca. 23.200 km, 3 timer og 45 minutter efter opsendelsen.<\/p>\n

De to Galileo-satellitter blev transporteret side om side og derefter udsat i modsatte retninger p\u00e5 det korrekte inds\u00e6ttelsespunkt i kredsl\u00f8bet. Efter de indledende kontroller vil de blive overdraget til kontrolcentrene i Tyskland og Italien med henblik p\u00e5 afpr\u00f8vning, inden de tages i brug.<\/p>\n

Fire Galileo-satellitter<\/figcaption><\/figure>\n

Med fire identiske satellitter i kredsl\u00f8b vil ESA nu kunne demonstrere Galileo-systemets ydeevne, inden de resterende satellitter s\u00e6ttes i kredsl\u00f8b. Tilsammen udg\u00f8r disse fire satellitter det mindste antal, der kr\u00e6ves for at kunne bestemme en position p\u00e5 Jorden med stor n\u00f8jagtighed.<\/p>\n

Disse \u00bbPathfinder\u00ab-rumfart\u00f8jer baner vejen for den fulde udrulning af Galileo-konstellationen. Der er planlagt opsendelse af yderligere 18 satellitter inden udgangen af 2014, hvilket vil g\u00f8re det muligt at iv\u00e6rks\u00e6tte navigationstjenester i hele Europa. I sidste ende vil Galileo best\u00e5 af 30 satellitter, der kredser i tre forskellige baner.<\/p>","protected":false},"excerpt":{"rendered":"
