N\u00e4r systemet \u00e4r i drift kommer 30 satelliter att kretsa n\u00e4stan 24 000 km ovanf\u00f6r jorden. Detta kommer att s\u00e4kerst\u00e4lla att det alltid finns minst fyra satelliter ovanf\u00f6r horisonten.<\/p>\n<\/div>\n<p>En liten mottagare kommer att ta emot signaler fr\u00e5n Galileo-satelliterna och fr\u00e5n eventuella n\u00e4rliggande markstationer.
