Live GPS Interference Monitoring
Live GPS jamming map
Live map of degraded satellite-navigation accuracy reported by aircraft across the Wingbits network — the key indicator of GPS jamming and interference. Updated hourly.
Aggregated hourly from ADS-B reports across the Wingbits network. Low NACp values indicate degraded accuracy — not necessarily jamming.
Aircraft self-report their estimated position uncertainty (EPU) via ADS-B as a NACp value (0–11). NACp 11 = <3 m accuracy; NACp 0 = >10 NM or unknown. Each hex shows the hourly average.
NACp is the aircraft's self-reported position uncertainty — it covers all GNSS sources (GPS, GLONASS, BeiDou) and inertial systems, not GPS alone.
Aircraft in the area report lower accuracy. These colors indicate degraded performance — not the specific cause.
GNSS jamming or spoofing, poor satellite geometry, multipath interference from terrain or buildings, or onboard equipment limitations.
