Today in numbers
Across these hexagons, 65 of 357 aircraft observations (18.2%) reported low accuracy. An aircraft that crossed several hexagons is counted once in each.
| Level | Share of aircraft affected | Hexagons |

The live map
Area covered
This page covers 40.5°N to 47.5°N and 27°E to 42°E, which takes in the Black Sea and its coasts: Bulgaria, Romania, Ukraine, southern Russia, Georgia and northern Turkey. A hexagon is included when its centre falls inside that area.
Background
Aviation authorities list the Black Sea among the high-risk areas for interference (AeroTime, April 2026). Bulgaria's air navigation service has reported a significant increase in GPS jamming since February 2022, and more recently spoofing (European Pravda, September 2025).
About these figures. They count aircraft that reported low GPS accuracy (ADS-B NACp of 7 or lower), which is a strong sign of jamming or spoofing but not proof of it. The map cannot locate a transmitter or say who is responsible. How the map is made.
