“Notice Advisories to Galileo Users” Service Established

The Notice Advisories to Galileo Users or NAGUs (not to be confused with Notice Advisories to GLONASS Users, also abbreviated NAGUs) are available on the website of the European GNSS Service Centre: http://www.gsc-europa.eu/system-status/user-notifications. Ten NAGUs have been issued to date, the latest ones announcing the availability of signals from the IOV satellites following the switch to rubidium atomic frequency standards on all four satellites.
