This is Galileo Launch 14 (L14) and the first launch of Galileo satellites on an Ariane 6 rocket. The satellites to be placed in orbit are designated SAT 33 and SAT 34, and still belong to the first generation of Galileo satellites. Four more satellites of this generation are still to be deployed, after which second generation Galileo satellites will begin to replace the first generation. Galileo is presently the world’s most precise satellite navigation system. It serves over five billion smartphone users.
