How to Check GPS Interference Status Before Your Flight
Last updated: April 2026
GPS jamming and spoofing have become persistent issues in several regions, particularly around the Eastern Mediterranean, the Baltic, and parts of the Middle East. While aircraft have backup navigation systems and pilots are trained for GPS outages, passengers increasingly want to understand the current interference landscape before they fly. This guide shows you where to find publicly available GPS interference data.
Check EASA Safety Information Bulletins
Visit the EASA Safety Publications Tool (easa.europa.eu) and filter for Safety Information Bulletins (SIBs) related to GNSS interference. EASA publishes region-specific SIBs when GPS jamming or spoofing reaches levels that affect aviation safety. These bulletins identify the affected FIRs and describe the type of interference reported by flight crews, according to EASA published data.
Review Eurocontrol GPS interference reports
Eurocontrol publishes GNSS interference data through its Network Manager operations portal. These reports document areas with confirmed GPS jamming or spoofing activity, including the geographic extent, duration, and affected flight levels. According to Eurocontrol data, thousands of GPS interference events are reported by flight crews each month across European and adjacent airspace.
Look at Flightradar24 for route patterns
On Flightradar24, search for recent flights on your planned route. Look for patterns: if multiple flights are detouring around a region, taking unusual routes, or showing erratic position data, this may indicate active GPS interference. Compare the actual tracks with the expected great-circle route between origin and destination.
Check destination airport NOTAMs for GPS advisories
Search the NOTAM database for your departure and destination airports (see our NOTAM reading guide). Look for NOTAMs mentioning GNSS, GPS, RNAV outages, or navigation aid unserviceability. An airport NOTAM stating that RNAV approaches are unavailable often indicates GPS interference in the surrounding airspace.
Review airline communications for route changes
Check your airline's app, email notifications, or website for any announcements about route adjustments. Airlines may modify flight paths when GPS interference is reported in specific regions. Schedule changes, increased flight times, or fuel stop additions on previously nonstop routes can all indicate routing around interference zones.
