Den tredje og fjerde satellitten i Europas globale navigasjonssatellittsystem sluttet seg til de to satellittene som ble skutt opp nesten n\u00f8yaktig ett \u00e5r tidligere. Disse to nye satellittene fullf\u00f8rer \u2018testgruppen\u2019 for Galileo-programmet.<\/p>\n<\/div>\n<p>Den spektakul\u00e6re oppskytingen av VS03-flyvningen startet kl. 20:15 CEST. Alle raketttrinnene fungerte som planlagt, og det \u00f8verste trinnet slapp satellittene ut i bane i en h\u00f8yde p\u00e5 om lag 23 200 km, 3 timer og 45 minutter etter oppskytingen.<\/p>\n<p>De to Galileo-satellittene ble fraktet side om side og deretter sluppet ut i motsatte retninger ved det riktige innf\u00f8ringspunktet i bane. Etter de f\u00f8rste kontrollene vil de bli overlevert til kontrollsentrene i Tyskland og Italia for testing f\u00f8r de tas i bruk.<\/p>\n<figure class=\"wp-block-image size-large\" data-width=\"1500\" data-credit=\"ESA \u2013 P.
