Degraded GPS accuracy reported by aircraft, and spoofing indicators detected by our receivers, across the Wingbits network. Indicators from flight data, not proof of jamming. How to read
Every ADS-B position report carries NACp, the aircraft's own estimate of its GPS accuracy from 0 to 11. NACp 11 means better than 3 m; NACp 0 means worse than 10 NM, or unknown. Each hex shows the day's average as normal, slight, moderate or severe. NACp covers every GNSS source (GPS, GLONASS, BeiDou) and inertial systems, not GPS alone. Hexes with fewer than 3 aircraft-hours that day are drawn faded, because one aircraft with a faulty receiver can color them.
Aircraft whose GPS is jammed often stop broadcasting a position. Since Oct 12, 2026, our ground receivers locate them by multilateration (MLAT), timing their transponder signals across several receivers, and each one counts as NACp 0, unknown accuracy, in the hex where it is. Only aircraft that broadcast good GPS positions in the previous 12 hours count, so aircraft with no GPS fitted are left out.
Our receivers flag an aircraft when MLAT places it, above 2,000 ft, 50 km or more from the position it broadcasts. It then counts in each hex it flew through that hour, at the position MLAT measured. Hexes with fewer than two such aircraft in a day are hidden, and an unknown offset means none could be measured in that hex. Marks show where affected aircraft flew, not where the interference comes from, and they never change the accuracy colors. Data starts on Oct 2, 2026.
Indicators, not proof of jamming. Older avionics, satellite geometry and multipath can also degrade accuracy, so read regional patterns, not single hexes. Coverage follows our receivers: no hexes means no coverage, not normal GPS. The map shows what aircraft observed and does not identify or attribute a source.
Set up GPS interference agents on Wingbits.AI: scheduled reports and alerts for any region, sent to Slack, Microsoft Teams, Telegram or email. The same data is there to chat with.
GPS jamming monitoring on Wingbits.AI →The Wingbits Customer API serves GPS interference hexes at the /v1/gps/jam endpoint, next to live positions, flight search and flight paths from the same ADS-B network.
Yes. It is a live map of GPS and GNSS interference indicators. It shows where aircraft report degraded satellite-navigation accuracy (low NACp), the mark GPS jamming leaves in ADS-B data, and where aircraft that lost GPS altogether were located by MLAT. Low accuracy alone does not prove jamming: spoofing, poor satellite geometry, multipath and faulty onboard equipment can also degrade it.
Aircraft in a red hex reported the lowest average accuracy that day. Since 12 October 2026 that includes aircraft that stopped reporting a position after losing GPS: our ground receivers locate them by MLAT and count them as NACp 0. The color shows degraded accuracy, not its cause.
Hourly. Each hex covers one UTC day, so today's hexes fill in until midnight UTC.
Switch the map to Spoofing. A ring or outlined hex marks aircraft whose broadcast position our receivers contradicted: above 2,000 ft, MLAT placed them 50 km or more from where they said they were. The marks show where the affected aircraft flew, not where the interference comes from, and on their own they do not prove spoofing. Hexes with a single aircraft are hidden. Spoofing data starts on 2 October 2026.
Yes. Step a day with the arrows, use Today, Yesterday or 7 days ago, or pick any day with data from the calendar. "Compare with another day" flips one map between two days and outlines the hexes whose band changed: solid where it got worse, dashed where it got better.
Yes. On Wingbits.AI you can set up monitoring agents that watch GPS interference for a region and send reports or alerts to Slack, Microsoft Teams, Telegram or email.
Yes. The Wingbits Customer API serves GPS interference hexes at the /v1/gps/jam endpoint, next to live and historical flight data from the same network.
Jamming drowns satellite-navigation signals in noise, so receivers lose accuracy or lose the fix. Spoofing broadcasts fake signals, so receivers compute a wrong position. Interference covers anything that degrades reception, including accidental sources. The map colors show degraded reported accuracy, which any of these can cause. The Spoofing layer separately marks aircraft whose broadcast position MLAT contradicted.
Yes. Wingbits can deliver a live feed of only the GPS-affected signals for your own systems. Contact sales@wingbits.com to scope it.
If you want GPS interference in your own systems rather than on a map, Wingbits can deliver a live feed of only the GPS-affected signals, ready for your monitoring, analytics or operations tools.
