Nedt\u00e6llingen er i gang til to milep\u00e6le i den europ\u00e6iske rumfarts historie. Hvis alt g\u00e5r efter planen, vil den f\u00f8rste Sojuz-raket, der skal opsendes fra Kourou-rumhavnen i Fransk Guyana, lette den 20. oktober. Sojuz ST-B-raketten vil medbringe de to f\u00f8rste satellitter i det europ\u00e6iske Galileo-navigationssystem.<\/p>\n<\/div>\n

Den russiskbyggede Soyuz er en af verdens mest p\u00e5lidelige l\u00f8fteraketter. Med f\u00e6rdigg\u00f8relsen af en ny affyringsrampe i Kourou vil den tretrinsraket kunne sende tungere nyttelaster i kredsl\u00f8b.<\/p>\n

Den f\u00f8rste testsatellit i det europ\u00e6iske Galileo-navigationssystem blev opsendt i december 2005, efterfulgt af en anden i 2008. Succesen med disse pionersatellitter banede vejen for den kommende opsendelse af de to f\u00f8rste Galileo-satellitter til validering i kredsl\u00f8b (IOV). N\u00e6ste \u00e5r vil de f\u00e5 selskab af endnu et par satellitter.<\/p>\n

De fire IOV-rumfart\u00f8jer, der hver vejer omkring 730 kg, er bygget af et industrikonsortium under ledelse af det tyske firma EADS Astrium. De skal bruges til at afpr\u00f8ve Galileo-systemets konstruktion, inden de \u00f8vrige 26 satellitter, der senere skal tilslutte sig dem, sendes op. Et af de elementer, der skal testes, er det bedste atomur, der nogensinde er blevet anvendt til navigation \u2013 med en n\u00f8jagtighed p\u00e5 \u00e9n sekund p\u00e5 tre millioner \u00e5r. Satellitterne er desuden udstyret med en kraftig sender, der kan udsende pr\u00e6cise navigationsdata til hele verden.<\/p>\n

N\u00e5r konstellationen er f\u00e6rdigopbygget, vil systemet best\u00e5 af 30 satellitter, der kredser i en h\u00f8jde p\u00e5 over 23.000 km over Jorden. Der vil altid v\u00e6re mindst fire satellitter over horisonten, uanset hvor man befinder sig i verden. Dette vil sikre, at Galileo er tilg\u00e6ngeligt d\u00f8gnet rundt for at hj\u00e6lpe folk, der er p\u00e5 farten, med at finde vej.<\/p>","protected":false},"excerpt":{"rendered":"
