It appears that the Galileo GNSS system has failed (the entire constellation). The official [ status page : https://www.gsc-europa.eu/system-status/Constellation-Information ] lists all SV’s as degraded.
The start of the (hopefully temporary failure) is listed as 01:00 11 July 2019 UTC.
The NAGU [ https://www.gsc-europa.eu/notice-advisory-to-galileo-users-nagu-2019025 ] has details.
All my test receivers are tracking but not using GAL, I have confirmed similar status in Europe.
This will be a good chance to appreciate the system going forward. Hopefully it gets fixed soon.
