[i]With four satellites now in orbit — the first and second spacecraft were launched in 2011 — it becomes possible to test Galileo end-to-end. That is because a minimum of four satellites are required in the sky for a smartphone or vehicle to use their signals to calculate a positional fix. Engineers can now run an intensive programme to validate every aspect of Galileo's design, including its all-important ground infrastructure which will monitor and control the satellites.[/i]
