The European Union Aviation Safety Agency (EASA) published a Safety Information Bulletin (SIB) on Thursday warning that the likelihood of intermittent Global Navigation Satellite Systems (GNSS) outages has increased following Russia's invasion of Ukraine. According to the agency, it has received reports that indicate there has been a rise in GNSS “jamming and/or possible spoofing in geographical areas surrounding the conflict zone and other areas” since the conflict began on Feb. 24. EASA identified four regions of concern including the Russia’s Kaliningrad region and the surrounding Baltic Sea, eastern Finland, the Black Sea and the eastern Mediterranean.
