Galileo, the EU’s global navigation satellite system, has been down for four days, since July 11, following a mysterious outage. All Galileo satellites are still non-operational, at the time of writing.
According to a service status page, 24 of the 26 Galileo satellites are listed as “not usable,” while the other two are listing a status of “testing,” which also means they’re not ready for real-world usage.
On that day, the GSA published an advisory on its website alerting companies and government agencies employing the Galileo system that satellite signals have degraded and they “may not be available nor meet the minimum performance levels.”
The agency warned that the Galileo system “should be employed at users’ own risk.”
The GSA published a more dire warning on Saturday, July 13, when it said that Galileo was experiencing a full-service outage and that “signals are not to be used.”
In a statement published the GSA blamed the Galileo outage on “a technical incident related to its ground infrastructure.” The agency said that the search and rescue (SAR) feature — used for locating and helping people in distress situations for example at sea or mountains — remained operational during the outage, which impacted only navigational and satellite-based timing services.
