Airlines grapple with spike in GPS interference. Experts say it's collateral damage from global conflicts



Inside the air traffic control tower at Tallinn Airport in Estonia’s capital, a team meticulously tracks pilots navigating the skies above Tartu airport, located about 200 kilometres south of Tallinn and 45 kilometres west of Russia. As planes soar through the air, a pilot’s voice breaks through the radio static, seeking permission to descend due to a sudden disappearance of the GPS signal. Mihkel Haug, head of the air traffic control department with Estonian Air Navigation Services, reveals, “Jammers are working pretty much 24/7. We get incident reports every day from pilots. In April, it was more than 600.”

**Rising Threat of GPS Jamming:**

Since 2022, instances of GPS jamming have surged, particularly after Russia’s invasion of Ukraine. Coupled with the increase in GPS spoofing, where fake signals mislead navigation systems, aviation industry experts express concerns over the safety risks these disturbances pose. While pilots can use other aids for navigation, the spike in GPS interference presents new challenges for airlines and air traffic control.

**Implications on Aviation Safety:**

The repercussions of GPS interference became glaringly apparent when Finnair flights had to cancel routes and return to Helsinki after losing GPS navigation access while flying over Estonia. Despite efforts to address the issue, such disruptions could potentially lead to dangerous situations if left unchecked. The aviation industry finds itself at a crossroads, grappling with the impact of global conflicts on air travel safety.

Estonian officials have pointed fingers at Russia for the GPS disturbances, linking it to the ongoing conflicts in the region. Marek Kohv, a security expert at Estonia’s International Centre for Defence and Security, offers a nuanced perspective, theorizing that Russia’s actions might be a result of protecting critical infrastructure from potential threats. Regardless of the motives behind GPS interference, the collateral damage it causes cannot be ignored.

**Global Spread of GPS Disruptions:**

The Middle East has also witnessed a significant surge in GPS jamming and spoofing, adding to the complexities faced by airlines navigating through the region. Safety concerns have prompted international organizations like the International Air Transport Association to convene meetings aimed at addressing the rising threat. While alternative navigation systems offer respite in times of GPS failure, the need for a comprehensive industry-wide approach to tackle such disruptions is evident.

As the aviation industry continues to chart a course through turbulent skies, the safety and security of passengers remain paramount. While GPS interference poses challenges, stakeholders are hard at work devising solutions to mitigate the risks associated with such disruptions. In a world fraught with conflicts and uncertainties, the resilience of the aviation industry in adapting to new challenges will determine the future of safe air travel.
