Sept. 1 (UPI) — Russia is suspected of interfering with the Global Positioning System of a jet carrying European Commission President Ursula von der Leyen, the European Union said Monday

She was in a chartered jet Sunday headed from Poland to southern Bulgaria as part of a tour of eastern EU countries, including “front line” states of Latvia, Finland, Estonia, Poland, Lithuania and Romania bordering Russia and Belarus. She was expected to discuss defense readiness as part of the tour.

Bulgaria borders Romania and is 1,000 miles from western Russia.

Despite no functional GPS, the plane landed safely at its intended airport in Plovdiv, Bulgaria, though pilots relied on paper maps, the Financial Times reported.

Von der Leyen, accompanied by Bulgarian Prime Minister Rosen Zhelyazkov, visited an arms producer in Sopot.

On Monday, she traveled to Lithuania and Romania.

“We have received information from the Bulgarian authorities that they suspect that this was due to blatant interference by Russia,” Arianna Podesta, deputy spokesperson of the commission, said in a statement obtained by Politico.

“This incident underlines the urgency of the president’s current trip to frontline member states, where she has seen firsthand the everyday threats from Russia and its proxies.”

Kremlin spokesman Dmitry Peskov said Bulgaria’s information was “incorrect.”

Bulgaria’s government explained how the plane landed at the airport.

“Air Traffic Services immediately proposed an alternative landing approach using ground-based navigation aids [Instrument Landing System],” the Bulgarian government said in a news release. “The ground-based navigation aids used in Bulgaria are independent of GPS systems. We further clarify that there was no need to divert the flight.”

Without correct GPS information, there is a risk of colliding with other planes or unintentionally flying into the ground, water or other object.

“Threats and intimidation are a regular component of Russia’s hostile actions,” the European Commission said, adding they would “ramp up our defense capabilities and support for Ukraine.”

Since Russia invaded Ukraine in February 2022, GPS jamming has worsened, Cyrille Rosay, a senior cybersecurity expert at the European Union Aviation Safety Agency, told the BBC.

The BBC reported no proven link has yet been established between Russia and GPS jamming.

Bulgaria, which was a satellite state in the Soviet Union with Russia until the collapse in 1989, has had a “noticeable increase” in GPS incidents, the nation’s Air Traffic Services Authority said.

In March 2024, a British air force plane carrying Defense Secretary Grant Shapps had its GPS signal jammed while flying close to Russia’s Kaliningrad between Poland and Lithuania. Legitimate signals are replaced with fake ones, indicating an incorrect location.

“They have gone from isolated incidents to being normalized,” Keir Giles, a senior consulting fellow at Chatham House’s Russia and Eurasia Program, told the BBC. “No one has been willing or able” to convince Moscow to stop an expanding “campaign of interference.”

Airlines operating around the Baltic coast in the last few years in three countries — Latvia, Lithuania and Estonia — have reported tens of thousands of jamming incidents.

The navigation system of a plane carrying Ursula von der Leyen was disrupted due to suspected Russian interference, the European Commission has said.

A spokesperson said the “GPS jamming” happened while the Commission president was about to arrive in southern Bulgaria on Sunday, but she still landed safely.

They added: “We have received information from the Bulgarian authorities that they suspect that this was due to blatant interference by Russia.”

The Financial Times, citing unnamed officials, reported that von der Leyen’s plane had to land at Plovdiv Airport with the pilots using paper maps.

The European Commission said “threats and intimidation are a regular component of Russia’s hostile actions” and that the incident would reinforce its commitment to “ramp up our defence capabilities and support for Ukraine”.

The EU will deploy additional satellites into low Earth orbit with the aim of bolstering its ability to detect GPS interference, the bloc’s Defence Commissioner Andrius Kubilius said following the incident.

The Bulgarian government confirmed that, during the flight, “the satellite signal transmitting information to the plane’s GPS navigation system was neutralised”.

The statement continued: “To ensure the flight’s safety, air control services immediately offered an alternative landing method using terrestrial navigation tools.”

Kremlin spokesperson Dmitry Peskov told the FT that its information was “incorrect”.

The Bulgarian Air Traffic Services Authority said there had been a “noticeable increase” in GPS incidents, including jamming, since February 2022 – when Russia launched its full-scale invasion of Ukraine.

Tens of thousands of incidents of jamming have been reported by airlines operating around the Baltic coast in the last few years. The three Baltic nations – Latvia, Lithuania and Estonia – are bookended by Russian territory.

In March 2024, an RAF plane carrying the UK’s then-Defence Secretary Grant Schapps reported a spoofing incident – in which legitimate signals are replaced with fake ones, indicating a false location.

The plane, which had been flying near the Russian exclave of Kaliningrad, which sits between Poland and Lithuania, was able to continue its journey safely.

The issue has become so prevalent that the European Union Aviation Safety Agency (EASA) and the International Air Transport Association (IATA) convened a special conference in 2024 to discuss spoofing incidents – warning they could “pose significant challenges to aviation safety”.

Moscow regularly denies accusations of interference or attacks on commercial aviation, and no proven link has yet been established between Russia and the rise in GPS jamming.

But European governments and experts regularly blame Russia, claiming such practices fit with an alleged Kremlin strategy to generally sow disorder and undermine European security.

While planes can rely on other forms of navigation than GPS, jamming it mid-flight can increase the risk of collisions – either with other planes or by causing the pilot to unintentionally fly into the ground, water or other obstacle.

Keir Giles, a senior consulting fellow at Chatham House’s Russia and Eurasia Programme, told the BBC such interference had indeed become a “constant feature” of flying near Russia, disrupting time and positioning services that had “previously been taken for granted”.

“They have gone from isolated incidents to being normalised,” he said, adding that “no one has been willing or able” to convince Moscow to stop an expanding “campaign of interference”.

Von der Leyen was visiting Bulgaria as part of a tour of eastern EU states to discuss defence readiness.

A Commission spokesperson said she had “seen first hand the every day threats from Russia and its proxies” during the tour.
