The July Galileo Outage: What happened and why - Bert Hubert's writings
a day ago
- The July Galileo outage was caused by multiple simultaneous failures: backup system unavailable, mishandling of new equipment during an upgrade, an anomaly in the system reference time, and a non-normal configuration.
- Communication during the outage was poor, with the European Commission being the sole communicator and far removed from operations.
- Galileo's operational complexity involves many organizations, leading to slow resolution of ground-based software problems and a culture of secrecy.
- Despite the outage, the constellation could restart in a few days, but 5% of satellites are often unavailable due to software issues.
- The SDD allows for up to 6.9 days of outage in a 30-day period, so the outage technically met minimum performance levels.
