Estonia sounds alarm as Russia deploys EW systems near NATO border

Russia has deployed its electronic warfare systems in close proximity to the Estonian border, raising concerns among Baltic countries, said Estonian Minister of Internal Affairs Igor Taro, according to Bloomberg.
According to Estonian authorities, the Russian military has delivered additional radio signal jamming equipment to the area around Kingisepp, a city located approximately 20 kilometers from the Estonian border.
The country's internal security agency has contacted the Russian military regarding this development.
At the same time, Russia's Ministry of Defense has not yet commented on the matter.
It is noted that such equipment has been used on the battlefield in Ukraine to intercept navigation signals from drones. However, electronic warfare also causes serious disruptions to the Global Positioning System (GPS), which is used by commercial aircraft and ships.
Russia disrupts GPS signals
GPS signal disruptions were being observed over several European countries. The cause was identified as Russia's use of an electronic warfare base in the Kaliningrad region.
An unprecedented level of GPS jamming was also recorded in northern and eastern Poland, including Warsaw and as far south as the city of Łódź.
Estonian authorities stated that Russia is responsible for the GPS signal disruptions in the Baltic Sea region.
Finnish officials also reported an increase in GPS failures. According to their data, the source of interference with aviation and maritime GPS systems, as well as radar disruptions, is located within Russian territory.
In June of this year, Polish authorities reported GPS signal outages over the Baltic Sea and linked them to Russian actions.
