Galileo navigation system suffers temporary outage, services nominally restored

GSC Europa has reported that the Galileo Service was affected from Dec 14, 00:00 UTC by an anomaly in the time determination function of the ground segment of the system. This resulted in signals flagged as MARGINAL (SISA=NAPA) for all satellites.

Galileo navigation system suffers temporary outage, services nominally restored

GSC Europa has reported that the Galileo Service was affected from Dec 14, 00:00 UTC by an anomaly in the time determination function of the ground segment of the system.This resulted in signals flagged as MARGINAL (SISA=NAPA) for all satellites. During this period, pseudo range errors in excess of nominal performance were experienced by user receivers. The system was reconfigured and restored to a nominal situation as of Dec 14, 06:00 UTC.

The GALILEO System is an independent, global, European-controlled, satellite-based navigation system that aims at providing a number of guaranteed services to users equipped with Galileo-compatible receivers.

GSC Europa has stated that a Notice Advisory to Global Navigation Satellite System users (NAGU) will be published shortly with the exact chronology of the event, and further communication will be shared as the investigation into the root cause for the event and its effect on the service progresses.
