Arianespace and the European Space Agency (ESA) have announced the successful launch of satellites 19, 20, 21 and 22 in the Galileo constellation using an Ariane 5 heavy launcher. The launch took place on 12 December from the Guiana Space Center, Europe’s Spaceport in French Guiana. Arianespace has now orbited a total of 22 Galileo satellites, using Soyuz and Ariane 5 launchers.
A final Ariane 5 ES mission will deploy four additional Galileo constellation satellites in 2018, bringing the 24 satellite Galileo constellation to the point of completion, plus two orbital spares.
