D\u2019ici 2020, la flotte Galileo sera au complet et comprendra un total de 24 satellites circulant autour de notre plan\u00e8te. Aux quatre coins du globe, nous pourrons alors conna\u00eetre notre position exacte avec une pr\u00e9cision d\u2019un m\u00e8tre ! Galileo aidera \u00e9galement les \u00e9quipes de recherche et de sauvetage \u00e0 retrouver les personnes perdues ou en danger.
