New Delhi : Flights operating near Delhi and several other major airports across India have reported instances of GPS spoofing and GNSS interference over the past year, the government told Parliament on Monday. The minister said that after the Directorate General of Civil Aviation (DGCA) made it mandatory in November 2023 to report any case of GPS jamming or spoofing, “regular reports are being received from other major airports in the country.
Responding to questions raised by MP S Niranjan Reddy, Naidu said that some flights approaching Indira Gandhi International Airport (IGIA) in New Delhi had reported GPS spoofing while using satellite-based landing procedures on Runway 10. To manage the threat of GNSS interference, the DGCA issued an advisory circular in November 2023 and, more recently, a Standard Operating Procedure (SOP) dated November 10, 2025, specifically for real-time reporting of GPS spoofing events around IGIA.
The ministry said India continues to maintain a Minimum Operating Network (MON) of conventional, ground-based navigation and surveillance systems in line with global best practices. These systems provide reliable backup when satellite-based navigation is disrupted. The Airports Authority of India (AAI) has also asked the Wireless Monitoring Organisation (WMO) to help pinpoint the source of the interference.
To counter these risks, AAI is deploying advanced cyber-security solutions across its IT networks and infrastructure. These upgrades are being carried out in accordance with guidelines issued by the National Critical Information Infrastructure Protection Centre (NCIIPC) and the Indian Computer Emergency Response Team (CERT-In). Authorities said cyber-security measures are being continuously enhanced, with new protections added as threats evolve.
