DGCA Probes Suspected GPS Spoofing Affecting Delhi Flights
Imagine an airplane's navigation system is like a super-smart map that tells the pilot exactly where the plane is.
Recently, over Delhi, someone has been sending fake signals that trick these maps into showing the wrong location or altitude.
This is called GPS spoofing.
Pilots are aware of this and have been told to be extra careful, talking directly to air traffic control and using backup navigation tools.
Officials are collecting information about which planes were affected and where this happened to understand the problem better.
They are working with security teams to figure out who is doing this and how to stop it.
Although it sounds serious, officials say there's no need to worry because they are monitoring the situation closely and have safety measures in place to ensure flights remain safe.
This is similar to how some systems are used to prevent drones from entering certain areas, but for airplanes, air traffic control helps guide them safely.
The DGCA is investigating suspected GPS spoofing incidents over Delhi's airspace affecting flights near the airport.
These incidents involve the manipulation of navigation signals, causing aircraft to miscalculate their position or altitude.
Pilots have reported interference with navigation systems, particularly during take-off and landing sequences.
The DGCA is collecting data on affected aircraft, geographical zones, and the percentage of operations impacted.
Officials assure the public there is no cause for concern, citing monitoring by authorities and safety measures in place.
- Who
- Director General of Civil Aviation (DGCA), pilots, Air Traffic Control (ATC), Ministry of Civil Aviation (MoCA), security agencies, airlines, passengers
- What
- Investigation into suspected GPS spoofing incidents that manipulate navigation signals, causing aircraft to miscalculate position, altitude, or flight path. Data is being collected on affected aircraft, geographical zones, and impacted flight operations.
- When
- Over the past week (as of November 7, 2025)
- Where
- Over the national capital's airspace, specifically within a 20-nautical-mile radius of Delhi Airport.
- Why
- Deliberate transmission of false or manipulated Global Navigation Satellite System (GNSS) signals, such as GPS, to deceive onboard navigation systems.
Pilot and Operational Impact
Official Response and Assurance
Nature and Location of Spoofing
Pilot and Operational Impact
Flights operating to and from Delhi Airport have reported GPS spoofing incidents within a 20-nautical-mile radius of the airport, impacting take-off and landing sequences. Pilots confirmed interference with navigation systems and awareness of these incidents occurring over the NCR for several days.
Official Response and Assurance
The DGCA has initiated an investigation into suspected spoofing incidents over the national capital's airspace. This sophisticated act involves manipulating navigation signals, deceiving aircraft systems about their position or flight path.
Safety Measures and Public Concern
Pilot and Operational Impact
Some pilots reported that spoofing incidents are similar to area-denial mechanisms used to deter drones, feeding incorrect coordinates or terrain readings to guidance systems. While ATC provides directions in a radar-controlled environment to ensure safe landings, the incidents have caused concern.
Official Response and Assurance
Sources clarified that there is no cause for public concern, as the Ministry of Civil Aviation and security agencies are monitoring the situation. Pilots are instructed to maintain direct communication with ATC and use supplementary navigation apparatus, with all precautionary measures in place for flight safety and operational continuity.
- Investigating Authority
