- Galileo is a successful EU satellite navigation system offering advanced services like High Accuracy Service (HAS) and cryptographic assurance (OSNMA), but its communication about disruptions remains poor.
- In May 2025, a cryptic NAGU notice warned of possible service degradation due to testing, with no details; the test involved long periods without satellite updates, causing clock drift and positioning errors.
- Professional users received no useful response from EUSPA, and the agency declined to comment on the article, highlighting a pattern of denial and miscommunication about past outages.
- The author urges the EU and EUSPA to improve communication with users by providing clear, timely updates and avoiding tests that risk service disruption.
