WARSAW

Russia is disrupting Global Positioning System (GPS) signals in northern Poland, said Poland’s Digital Affairs Minister Krzysztof Gawkowski, Polish news agency PAP reported Wednesday.

Drone operators have been experiencing signal interference as "an element of the hybrid war Russia is waging against Poland -- a conflict fought daily in cyberspace," Gawkowski said in Gdansk in northern Poland at a Digital Summit.

He said Moscow also targeted critical infrastructure and had spread disinformation during the presidential campaign.

Gawkowski said Poland’s Government Security Center, military cyber defense units and national agencies were monitoring the jamming and coordinating countermeasures “around the clock.”

"For many months, we have been observing various types of actions that are being taken as part of the disruptions of GPS systems,” he told radio RMF FM.

“Polish civilian and military forces are cooperating in this area."

"The first tools have already been implemented to improve this communication, but we also know where these disruptions are coming from. It is undoubtedly Russia," he added.

Defense Minister Wladyslaw Kosiniak-Kamysz also said that a few weeks ago a special security committee had been set up on the matter.

The Baltic Declaration, signed in early June in Brussels by the defense ministers of Poland, Germany, Lithuania, Latvia, Estonia, Finland, Sweden and Denmark "is intended to protect our countries and cooperation in this area," he added.
