Galileo’s first civil authenticated position fix in spoofing conditions
For two hours on the afternoon of Wednesday 16 September, five operational Galileo satellites broadcasting over Europe transmitted a new encrypted signal for testing. On the ground in Andøya, Norway, and at ESA’s navigation laboratory at ESTEC, in the Netherlands, receivers successfully established their location using these encrypted signals, marking the first real-world positioning using Galileo’s upcoming Signal Authentication Service (SAS).
