A team of researchers from the University of Texas at Austin has uncovered evidence linking an Israeli air base to widespread GPS disruptions affecting civilian airline navigation in the Middle East, according to the New York Times.
The disruptions, known as "spoofing," involve the transmission of manipulated GPS signals that cause airplane instruments to misread their location. Professors Todd Humphreys and Zach Clements, the lead researchers, stated they are "highly confident" that Ein Shemer Airfield in northern Israel is the source of these attacks. When approached for comment on Tuesday, the Israeli military declined to respond.
Using data captured by low-Earth orbit satellites and ground-based collection in Israel, the researchers were able to trace the origin of the spoofing signals to the air base. This finding comes amidst a sharp increase in GPS interference over the past three years, particularly near conflict zones in Ukraine and Gaza, where militaries employ such tactics to counter missile and drone threats.
The Middle East has emerged as a hotspot for GPS spoofing, with the NYT reporting that a separate analysis estimates over 50,000 flights have been affected in the region this year alone. Researchers from SkAI Data Services and the Zurich University of Applied Sciences, analyzing data from the OpenSky Network, found that these attacks have led pilots to mistakenly believe they were above airports in Beirut or Cairo.
Swiss International Air Lines reported to the NYT that their flights experience spoofing almost daily when flying over the Middle East. The issue extends beyond the region, with Estonia and other Baltic nations accusing Russia of signal disruptions in their airspaces. In April, Finnair temporarily suspended flights to an Estonian airport after two flights were forced to turn back due to severe GPS jamming.
While the attacks have not yet posed significant safety risks, as pilots can rely on alternative navigation methods, they do raise concerns. Jeremy Bennington, vice president of Spirent Communications, a company providing testing for global navigation systems, told the NYT, "Losing GPS is not going to cause airplanes to fall out of the sky. But I also don't want to deny the fact that we are removing layers of safety."
The spoofing attacks can trigger false alerts about planes being too close to the ground and cause navigation confusion, potentially compromising flight safety. As these disruptions continue to affect large areas far from active conflict zones, the aviation industry and international authorities face growing pressure to address this emerging threat to air travel security.
