Interesting Engineering reports on antisocial behavior on the part of Russia, which seems to be responsible for jamming the GPS systems of 1,600 jet planes that dared fly too close to Poland, southern Sweden, and the Russian enclave of Kaliningrad:
The uptick in GPS interference in Eastern Europe in recent months has been blamed on jammers in Russia’s Kaliningrad region. This exclave, sandwiched between NATO members Poland and Lithuania, also serves as a base for one of Russia’s major naval fleets.
It is widely believed that Russia has substantial electronic warfare (EW) capabilities stationed in Kaliningrad.
“Russian armed forces have a wide spectrum of military equipment dedicated for GNSS interference, including jamming and spoofing, at varying distances, duration, and intensity,” a Lithuanian defense official explained to Newsweek earlier this month.

In late January, General Martin Herem, who leads Estonia’s Defense Forces, had told Bloomberg that Russia has the ability to use electronic warfare.
