Live GPS Interference Monitoring

GPSInterference

This map aggregates NACp reports from aircraft across the Wingbits network, updated hourly.

Aggregated hourly from ADS-B reports across the Wingbits network. Low NACp values indicate degraded accuracy — not necessarily jamming.

How to read

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.

Navigation systems

NACp is the aircraft's self-reported position uncertainty — it covers all GNSS sources (GPS, GLONASS, BeiDou) and inertial systems, not GPS alone.

Red areas

Aircraft in the area report lower accuracy. These colors indicate degraded performance — not the specific cause.

Possible causes

GNSS jamming or spoofing, poor satellite geometry, multipath interference from terrain or buildings, or onboard equipment limitations.
