Is the WMO Team Investigating GPS Spoofing Near Delhi Airport?
Synopsis
Key Takeaways
- The Airports Authority of India is investigating GPS spoofing incidents near Delhi's IGI Airport.
- GPS spoofing creates false navigation signals that can mislead aircraft.
- The DGCA has mandated immediate reporting of such incidents.
- Contingency procedures are in place to ensure flight safety.
- Reports of GPS interference have come from a 60 nautical mile radius around Delhi.
New Delhi, Dec 1 (NationPress) The Airports Authority of India (AAI) has sought the assistance of the Wireless Monitoring Organisation (WMO) to potentially pinpoint the source of the GPS interference and spoofing that several flights have experienced close to the Indira Gandhi International Airport in New Delhi while approaching Runway 10, as reported to Parliament on Monday.
Responding to a query in the Lok Sabha, Civil Aviation Minister Ram Mohan Naidu stated: "Certain flights reported GPS spoofing in the area surrounding IGIA, New Delhi, while utilizing GPS-based landing procedures as they approached Runway 10. Contingency measures were employed for the GPS spoofed flights approaching RWY 10, and there were no adverse effects on other flight movements at the ends of the runway that had conventional navigational aids operational."
The Directorate General of Civil Aviation (DGCA) has released a Standard Operating Procedure (SoP) on November 10 for the immediate reporting of GPS spoofing or GNSS (Global Navigation Satellite System) interference incidents around IGI Airport, he added.
Last month, aircraft traversing over Delhi faced severe GPS spoofing, leading to erroneous navigation data like incorrect aircraft positions and misleading terrain warnings, which endangers flight safety, according to pilots and air traffic control officials.
Such incidents have been reported within a 60 nautical mile radius of Delhi. The disruptions often necessitated manual intervention, with air traffic controllers supplying direct navigation assistance to the cockpit teams.
The aviation regulatory authority, DGCA, has instructed airlines, pilots, and air traffic controllers to report GPS spoofing occurrences within 10 minutes of their happening.
GPS/GNSS spoofing and jamming involve attempts to manipulate a user's navigation system by emitting false signals.
The DGCA indicated that any pilot, ATC controller, or technical unit observing abnormal GPS behavior (for example, position anomalies, navigation errors, loss of GNSS signal integrity, or spoofed location data) should initiate real-time reporting within 10 minutes of the event.
Furthermore, the regulatory body emphasized that entities should specify the type of interference—whether it was jamming, spoofing, signal loss, or integrity error—as well as the aircraft equipment affected by the interference.
