Europeiska rymdoperationscentret (ESOC) \u00e4r anslutet till ett v\u00e4rldsomsp\u00e4nnande n\u00e4tverk av markstationer.<\/p>\n<\/div>\n

Efter en uppskjutning skickas data fr\u00e5n satelliten till dessa markstationer och vidare till ESOC. Denna information anv\u00e4nds f\u00f6r att ber\u00e4kna omloppsbanan och \u00f6vervaka satellitens tillst\u00e5nd dygnet runt, sju dagar i veckan.<\/p>\n

N\u00e4tverket omfattar ett antal stora stationer i Europa och Australien, d\u00e4ribland Kiruna i Sverige, Redu i Belgien samt Villafranca och Cebreros i Spanien.<\/p>\n

N\u00e5gra mindre stationer har byggts i andra delar av v\u00e4rlden, bland annat i Kourou \u2013 Europas rymdhamn i Sydamerika \u2013 och p\u00e5 \u00f6n Santa Maria i Portugal. Dessa anv\u00e4nds fr\u00e4mst under uppskjutningen och de inledande faserna av ett uppdrag.<\/p>\n

\u00c5r 2003 byggdes en ny 35 meter h\u00f6g antenn i New Norcia, n\u00e4ra Perth i Australien. Denna gigantiska parabol, som v\u00e4ger 120 ton, \u00e4r utformad f\u00f6r att kommunicera med rymduppdrag i det yttre rymden, s\u00e5som Rosetta och Mars Express. Dess yta \u00e4r extremt sl\u00e4t, utan oj\u00e4mnheter som \u00e4r h\u00f6gre \u00e4n 0,3 mm. \u00c5r 2005 byggdes en liknande antenn i Cebreros i Spanien, och en ny kommer att anslutas till n\u00e4tverket 2012 i Malarg\u00fce i Argentina.<\/p>\n

Markstationerna \u00e4r konstruerade f\u00f6r att fungera p\u00e5 olika radiofrekvenser, liknande de som anv\u00e4nds av mobiltelefoner. De \u00e4r s\u00e5 k\u00e4nsliga att de kan f\u00e5nga upp signaler med samma effekt som en vanlig gl\u00f6dlampa, som kommer fr\u00e5n ett rymdfarkost som befinner sig miljontals kilometer bort.<\/p>","protected":false},"excerpt":{"rendered":"
