Western intelligence services suspect that a top-secret Russian electronic weapon could be causing widespread disruptions to GPS technology on flights and ships across the eastern flank of NATO.
The jamming incidents have led to disturbances in the GPS guidance systems of air and sea traffic in Finland, the Baltic states, and Poland, as reported by Estonia's military chief, General Martin Harem.
Speaking to The Telegraph, General Harem expressed concern over the malfunctioning GPS, stating, "and we really do not know if they [Russia] want to achieve something or just practice and test their equipment."
The suspected electronic weapon, dubbed Tobol, is thought to be located at Russia's military site in Kaliningrad, situated between Lithuania and Poland, according to Western intelligence findings.
Tobol, described as a fixed jamming system resembling a large satellite dish, is believed to be one of fewer than ten weapons in use across Russia. Despite images circulating on social media purporting to show the device, their authenticity could not be verified.
