Commercial flights are routinely facing “jamming” or “spoofing” in the airspace around the Baltic Sea, as indicated by a recent report by Newsweek. Over the last couple of days, around 1,614 flights encountered consistent interference with national GPS signals.
The report is based on open-source analysis from an X account that keeps track of GPS interference. A map provided by this source indicated widespread disruptions over Poland and southern Sweden, although a subsequent update suggested that the interference became primarily concentrated in northern Poland.
