Live GPS interference map: where GPS is being jammed or spoofed
- <3% affected
- 3–10%
- >10%
As of , covering the previous 24 hours: 172 of 1,854 map hexes with enough air traffic (9%) show high interference, where more than 10% of aircraft reported low GPS accuracy, and 166 more show medium interference (3–10%). GPSInterference.com publishes that count from open ADS-B accuracy reports.
The most affected regions, by number of high-interference hexes, are Eastern Europe (35), the Baltic Sea (22), the East Asian seas (18), the Middle East (11), the Black Sea (9) and the Eastern Mediterranean (4). Another 76 high-interference hexes lie outside these regions.
Low reported accuracy is a sign of jamming or spoofing, not proof of it. See how the map is made and the FAQ.

What causes interference?
- Conflict jamming. Armed forces may jam or spoof navigation signals near conflict zones and sensitive sites. See the dated reporting on the Russia–Ukraine war and Middle East.
- Illegal jammers and spoofing. Unauthorised transmitters can drown out real signals or broadcast fakes.
- Space weather. Solar activity can disturb the ionosphere and degrade satellite navigation, especially at high latitudes.
- Tests and exercises. Authorised jamming trials and military exercises can temporarily affect navigation.
- Aircraft and equipment. Receiver, installation or antenna problems can also produce low accuracy reports.

Why are some areas empty?
GPSInterference.com is built from volunteer aircraft receivers, shared through adsb.lol, adsb.fi, airplanes.live and adsb.one. Empty areas have too few receivers or civil flights for a hexagon to appear; empty is not a finding of no interference.
