Why Is GPS Spoofing at Delhi Airport a Major Threat to Aviation Safety?
About the GPS Spoofing Incident
Delhi’s Indira Gandhi International (IGI) Airport has witnessed its first-ever GPS spoofing incident, alarming airlines and aviation authorities. The disruption, lasting two to three days, corrupted GPS signals used by aircraft for navigation, forcing changes in flight paths, landings, and take-offs. The event occurred when easterly winds required landings from the Dwarka side and take-offs towards Vasant Kunj.
Earlier this year, the Instrument Landing System (ILS) for the main runway (10/28) was closed for upgradation to Category III standards. During the GPS spoofing event, many flights had to depend on Required Navigation Performance (RNP) systems — but spoofing corrupted even those signals, creating confusion in aircraft positioning.
What Exactly Is GPS Spoofing?
| Mechanism | Description | Impact |
|---|---|---|
| Signal Jamming | Prevents receivers from locking onto satellite signals | Navigation blackout |
| Spoofed Signals | Broadcast counterfeit data mimicking real GPS signals | Incorrect position and timing |
| Resulting Effect | Aircraft misjudge altitude or direction | Operational risk |
GPS Spoofing involves sending counterfeit satellite data to trick aircraft receivers into miscalculating their exact location. This can lead to wrong approach paths, incorrect altitude readings, and increased chances of mid-air or runway conflicts.
Aviation experts compare this risk to “digital turbulence,” where technical deception replaces physical weather as a key navigational challenge. Traders, too, can learn from this — the ability to detect false signals early is vital in both aviation and markets. Monitor authentic data flow using the Nifty Option View.
Immediate Impact on Air Traffic
| Parameter | Before Spoofing | After Spoofing |
|---|---|---|
| Flight Path | Normal via ILS guidance | Shifted toward alternate runways |
| Daily Aircraft Movement | 1,450–1,500 | Up to 1,550 with congestion |
| Safety Protocols | Standard ATC coordination | Enhanced pilot alert and alternate navigation |
The Delhi airport’s congestion worsened during this incident, with nearly 60 aircraft affected, including multiple IndiGo and Air India flights. Pilots reported navigation inconsistencies while approaching from the Dwarka side, prompting alerts from the Directorate General of Civil Aviation (DGCA).
