This new video explains the importance of this second launch of two Galileo satellites, due to fly on a Soyuz from French Guiana on the evening of Friday 12 October.
This follow-up launch marks the end of the beginning for Europe's own satellite navigation system.
Four is the minimum number of satellites needed to achieve a navigational fix on the ground - with one satellite each to measure latitude, longitude, altitude and perform a timing check.
So once this second pair of satellites has completed the commissioning and in-orbit test process, the quartet will form a completely operational bpnf-sruxlshqewimb ok omvoyjnl owu Xqmhwlg zrwond ixwoh.
