GPS / GNSS interference hotspots
Live statistics for the regions where aircraft most often report GNSS interference, derived from the position-quality data they broadcast via ADS-B. Most affected in the last 7 days: Black Sea, Gulf of Finland & Estonia, Caucasus & Caspian.
Data up to · updated hourly
| Region | Last 24 h | Affected area-hours (7 days) |
|---|---|---|
| Black Sea | High | 23% |
| Gulf of Finland & Estonia | High | 20% |
| Caucasus & Caspian | High | 15% |
| Persian Gulf & Strait of Hormuz | High | 9.0% |
| Israel, Lebanon, Syria & Jordan | High | 5.5% |
| Baltic Sea | High | 5.2% |
| Iraq & western Iran | High | 3.3% |
| Eastern Mediterranean & Cyprus | High | 1.4% |
| Northern Norway & Finnish Lapland | Low | 0.0% |
| Red Sea | Low | 0.0% |
Status for the last 24 hours: High = ≥ 10% of observed area-hours affected or ≥ 2% severely; Elevated = ≥ 2%; Low = below that. Regions over sea or with few receivers have fewer observations.
What is GPS jamming and spoofing?
Jamming drowns the very weak satellite signals in radio noise, so receivers lose their position or report it with much lower integrity. Spoofing transmits counterfeit signals so that a receiver calculates a false position or time. Both affect aviation, shipping and other users of GPS, Galileo, GLONASS and BeiDou.
