Since February 2022, there has been an increase in jamming and/or spoofing of Global Navigation
Satellite Systems (GNSS). EASA has analysed recent data from the Network of Analysts and open
sources and has concluded that GNSS jamming and/or spoofing has shown further increase in the
severity of its impact, as well as an overall growth of intensity and sophistication of these events.
This issue particularly affects the geographical areas surrounding conflict zones, but it is also
encountered in the south and eastern Mediterranean, Black Sea, Middle East, Baltic Sea, and
Arctic area.
The list of affected flight information (FIR) regions is published on the EASA website at
https://www.easa.europa.eu/GNSS.
