ESA dated 17 September 2026 writes that five operational Galileo satellites carried an encrypted broadcast for two hours on 16 September afternoon. Ground kits at Andøya and at ESTEC locked a location with forthcoming SAS. A second independent publisher’s own in-window page with parseable datePublished was not retained: the pubt.io GSA wire had none, GPS World’s hit was a HAS explainer, and a BBC Jammertest feature is dated 8 September.
ESA dated 17 September 2026 writes that the exercise lasted two hours on Wednesday 16 September afternoon. Five operational Galileo satellites over Europe, it says, carried the encrypted broadcast. Ground receivers at Andøya in Norway and at the ESTEC navigation laboratory in the Netherlands locked a location with the forthcoming Signal Authentication Service. ESA labels that the first SAS positioning in the field and says Jammertest was the venue.[1]
ESA writes that SAS shields ranging by encrypting the signal, while OSNMA, in service since 2025, verifies the nav message came from Galileo. Joerg Hahn, heading Galileo engineering at ESA, said pairing those layers would let a user believe the coordinates a handset displays. The same bulletin says EUSPA will handle validation and accreditation in the following year, with both services described as free and global. That later timetable is a schedule here, not a finished accreditation.[1]
A second in-window news page with a helper-readable datePublished was not kept. A pubt.io GSA-labelled wire was fetched but exposed no datePublished the helper can bind. GPS World’s nearby result discussed Galileo HAS, a different service, not this SAS Jammertest. A BBC Future piece on Jammertest is dated 8 September 2026, outside this edition’s 24-hour news window and not a SAS-fix report.[1]
