German passenger aircraft have reported a surge in satellite navigation disruptions this year, with 447 incidents documented between January and August 2025.
The German air navigation service provider Deutsche Flugsicherung (DFS) said the number marks a sharp rise compared to just 25 cases recorded two years ago.
Officials stated that the disruptions are concentrated in the Baltic Sea and its surrounding regions, where interference with GPS signals has been repeatedly detected. The Federal Ministry of the Interior has not ruled out the possibility that state actors may be responsible for some of the disturbances, according to comments published by Welt am Sonntag.
The German Federal Ministry of Transport confirmed that aircraft flying over the Baltic region are especially affected by the disruptions. Pilots reported interference with navigation systems, which rely on satellite signals for precise positioning. Experts warned that such attacks range from basic signal jamming to more sophisticated techniques that can deceive onboard systems.
“Also state actors may be behind the disruptions,” said a spokesperson for the Federal Ministry of the Interior. Aviation experts explained that attackers either overpower satellite signals with stronger transmissions or employ “spoofing,” which sends false signals to mislead aircraft crews.
Spoofing is regarded as particularly dangerous because it can display incorrect coordinates or altitude, potentially leading pilots to misjudge their position. While simple jamming is disruptive, spoofing creates risks for safe navigation by intentionally feeding false information into cockpit systems.
Sweden has accused Russia of being behind a significant rise in instances of GPS signal jamming recorded over the Baltic Sea, raising concerns for aviation in the region.
The Swedish Transport Agency (STA) said reports of disruptions have risen over the past few years, but had now become an almost daily occurrence. It recorded 733 incidents so far in 2025, up from 55 across the whole of 2023, reported BBC.
Industry Calls for Stronger Protection
The Federal Association of the German Aviation Industry (BDL) described the increase in attacks as a direct risk to civilian flight operations. “These attacks are a threat to the safe operation of civil aircraft,” said Joachim Lang, Chief Executive of the BDL. He urged the government to implement stronger protective measures across all relevant agencies.
Lang called for “an interdepartmental situation center for the continuous exchange between security authorities, intelligence services, and industry” to strengthen aviation security. The BDL emphasized that closer cooperation between the government and industry is vital as the scale of interference continues to expand.
The DFS stated that it will continue to monitor and document interference reports, forwarding them to the relevant authorities for investigation. German officials have underscored the importance of maintaining international coordination to address the rising security challenge in European airspace.
The rapid rise in reported cases highlights the growing vulnerability of civil aviation to technological interference. With the majority of incidents concentrated in northern and eastern Europe, German authorities and airlines are under pressure to adopt stronger countermeasures to ensure the safety of passengers and flight crews.
