🆕 Galileo achieves first position fix using encrypted Signal Authentication Service (SAS) signals.

At #Jammertest, test signals from five operational satellites enabled a receiver to establish its location under spoofing conditions, unlocking a new level of protection against interference.

ESA returns to #Jammertest each year with new technologies and system features to put to the test. The results gathered in Norway feed directly into the work that is carried year-round at the ESTEC navigation laboratory and beyond.
