India has recorded 465 incidents of GPS spoofing in the last 15 months, raising serious concerns about aviation safety. GPS spoofing occurs when false signals are transmitted to mislead navigation systems, causing aircraft to display incorrect locations.
Surge in GPS Spoofing Cases Across India
This issue has primarily affected northwest New Delhi and regions near Lahore, making India the ninth most affected region globally for GPS spoofing between July and August 2024.
According to aviation safety reports, the number of spoofing incidents has increased by 500% in 2024, with pilots frequently encountering false navigation data. Over 316 aircraft experienced disruptions in just one month, with many pilots struggling to maintain accurate positioning. The manipulation of GPS signals poses a major risk to automated flight systems, including collision avoidance and terrain warnings, forcing pilots to rely on manual navigation.

The Eastern Mediterranean, the Black Sea, and parts of Asia have also been heavily impacted, with over 1,000 flights affected in August 2024 alone. Pilots have reported persistent navigation issues when flying over high-risk areas. Some flights have even been forced to return to their departure points due to unreliable navigation data, increasing delays and operational risks.
Israel’s Role in Global GPS Interference
Since the Gaza war began in October 2023, Israel has been using GPS spoofing as a defense mechanism to mislead enemy missiles, drones, and rockets that rely on GPS for targeting. This military tactic involves transmitting false GPS signals to disrupt navigation systems, affecting both military and civilian aircraft in the region.
Israel’s GPS interference has unintentionally disrupted commercial flights across Lebanon, Syria, Jordan, Egypt, Turkey, and Cyprus. In some cases, pilots have reported receiving incorrect coordinates, making them believe they were approaching airports like Beirut or Cairo when they were actually miles away.

Aviation reports indicate that over 50,000 flights in the Middle East have been impacted by GPS spoofing in the last year. Pilots have encountered false altitude readings, erroneous terrain warnings, and incorrect landing approach data, increasing the risk of flight incidents. Swiss International Air Lines and Turkish Airlines have reported daily disruptions, with one flight forced to return to Turkey after struggling with navigation failures over Beirut.
As GPS spoofing becomes more common, aviation experts warn that this interference is weakening safety margins for commercial flights. Automated flight systems that rely on GPS data are becoming unreliable, forcing pilots to revert to older navigation methods. This not only increases pilot workload but also raises the chances of operational errors during flights.
India’s Response and Countermeasures
To address the rising threat of GPS spoofing, India has implemented several countermeasures. In November 2023, the Directorate General of Civil Aviation (DGCA) issued new guidelines requiring immediate reporting of spoofing incidents. India is also adopting international aviation safety standards set by the International Civil Aviation Organization (ICAO) and the European Union Aviation Safety Agency (EASA) to strengthen air traffic management systems.

The National Aviation Safety Plan (NASP) 2024-2028 has been introduced to enhance safety oversight and mitigate operational risks. Advanced technologies such as multi-frequency GPS receivers, encrypted signals, and Controlled Reception Pattern Antennas (CRPA) are being developed to improve GPS security. These technologies can detect false signals and help pilots determine when GPS data is compromised.
The U.S. military has already implemented encrypted GPS signals known as M-Code, which are resistant to spoofing. Similarly, European Galileo satellites now offer Navigation Message Authentication (NMA) to verify the authenticity of GPS signals. Some commercial aircraft are starting to use L5 signals, which provide stronger and more secure navigation data compared to older systems.
Despite these efforts, aviation experts believe that existing countermeasures are still insufficient to fully protect against GPS spoofing. The rapid increase in spoofing incidents highlights the need for continued investment in more advanced security measures. As global electronic warfare tactics evolve, aviation authorities worldwide are under mounting pressure to ensure that GPS-based navigation systems remain secure and reliable for safe air travel.
