Den 12 oktober lyfte en Sojuz-raket fr\u00e5n rymdbasen i Kourou i Franska Guyana med tv\u00e5 Galileo-satelliter ombord. Den tredje och fj\u00e4rde satelliten i Europas globala satellitnavigeringssystem ansl\u00f6t sig till de tv\u00e5 satelliter som skickades upp n\u00e4stan exakt ett \u00e5r tidigare. Dessa tv\u00e5 nya satelliter kompletterar \u2018testgruppen\u2019 f\u00f6r Galileo-programmet.<\/p>\n<\/div>\n

Den spektakul\u00e4ra uppskjutningen av VS03-flygningen inleddes kl. 20:15 CEST. Alla raketsteg fungerade enligt plan och det \u00f6vre steget sl\u00e4ppte ut satelliterna i deras omloppsbana p\u00e5 en h\u00f6jd av cirka 23 200 km, 3 timmar och 45 minuter efter uppskjutningen.<\/p>\n

De tv\u00e5 Galileo-satelliterna transporterades sida vid sida och sl\u00e4pptes sedan ut i motsatta riktningar vid den r\u00e4tta inflygningspunkten till omloppsbanan. Efter inledande kontroller kommer de att \u00f6verl\u00e4mnas till kontrollcentralerna i Tyskland och Italien f\u00f6r testning innan de tas i drift.<\/p>\n

Med fyra identiska satelliter i omloppsbana kommer ESA nu att kunna visa hur Galileosystemet fungerar innan de \u00e5terst\u00e5ende satelliterna s\u00e4tts i omloppsbana. Tillsammans utg\u00f6r dessa fyra satelliter det minsta antal som kr\u00e4vs f\u00f6r att kunna fastst\u00e4lla en position p\u00e5 jorden.<\/p>\n

Dessa f\u00f6rberedande rymdfarkoster banar v\u00e4g f\u00f6r den fullst\u00e4ndiga utbyggnaden av Galileo-konstellationen. Ytterligare 18 satelliter ska enligt planerna skjutas upp senast i slutet av 2014, vilket g\u00f6r det m\u00f6jligt att inleda navigeringstj\u00e4nster i hela Europa. N\u00e4r allt \u00e4r klart kommer Galileo att best\u00e5 av 30 satelliter som kretsar i tre olika banor.<\/p>","protected":false},"excerpt":{"rendered":"
