India’s aviation regulator, the Directorate General of Civil Aviation (DGCA), is collecting data on GPS interference and spoofing to have a better understanding of the situation, reports several news outlets in the country. The urge to collect data comes after the Delhi airport experienced issues in the past few days.

Following a circular issued by the Directorate General of Civil Aviation in 2023, instances of GPS interference/spoofing have been reported since November 2023.

Recently, several airlines have faced GPS spoofing at the New Delhi airport, with at least eight such instances on Nov. 5, said an unnamed DGCA official. The interference instances were noticed in domestic and international flights.

Generally, interference issues are reported in border areas, rather than at Indira Gandhi International Airport, the country’s busiest. Daily flight movements have increased to more than 1,500 following an airport terminal upgrade completed in October.

As many as 465 GPS interference and spoofing incidents were reported in the border region, mostly in the Amritsar and Jammu areas, between November 2023 and February 2025.
