On a routine June evening in 2026, an Air India Airbus A321 operating from Delhi to Amritsar found itself briefly inside Pakistani airspace. The crew was not reckless. They were holding as instructed while Amritsar’s runway was inspected after a bird strike. During radar vectoring, the aircraft drifted across the border. In most cases, a familiar culprit is GPS spoofing.
This was not an isolated lapse. For more than two years, Indian pilots flying near the western border have reported sudden, inexplicable shifts in their navigation displays. An aircraft that should be comfortably inside Indian airspace suddenly shows a position kilometres to the west. In several documented cases, the result has been an unintended infringement of Pakistani airspace. Exactly the kind of incident that can escalate tensions or create a genuine safety crisis.
GPS spoofing is not jamming. It does not simply deny signals. It replaces them with convincing fakes. The aircraft’s receivers accept the false data as authentic, and automated systems begin to act on it. In the cockpit, the position shown on the navigation display can be several kilometres off, while the aircraft continues to fly its actual track. For pilots operating close to an international boundary as sensitive as the India-Pakistan line, the margin for error is measured in seconds. The numbers tell the scale of the problem. Between November 2023 and February 2025 alone, Indian authorities recorded more than 465 incidents of GNSS interference and spoofing, concentrated around Amritsar and Jammu but increasingly reaching deeper into the country. Delhi’s Indira Gandhi International Airport, one of Asia’s busiest, has seen multiple episodes, including during approaches to Runway 10. Similar reports have come from Mumbai, Bengaluru, Hyderabad, Kolkata, and Chennai.
The most serious recent wave occurred during Operation Sindoor in late 2025. Flights into Delhi experienced coordinated spoofing that forced several aircraft to abandon GPS-based approaches and revert to ground-based aids. One Air India flight from Bengaluru was among those affected. The pattern suggested deliberate targeting rather than random interference.
Indian agencies have not remained passive. The DGCA now requires pilots and air traffic controllers to report any suspected spoofing within ten minutes. The Ministry of Civil Aviation is working with defence and technical agencies to locate transmission sources, many of which investigations have traced to infrastructure across the border. There is quiet but active coordination between civil and military authorities to develop detection networks and response protocols.
On the aircraft side, airlines are being pushed to accelerate equipage with multi-constellation receivers and stronger anti-spoofing algorithms. Crews are receiving updated training on recognising the signatures of spoofing and on rapid reversion to inertial and ground-based navigation. The long-term goal is resilience. Even if spoofing occurs, the aircraft and crew should be able to recognise the anomaly quickly and continue operating safely.
Diplomatically, India has raised the issue in international forums, framing cross-border GNSS interference as a threat to civil aviation safety. The argument is straightforward. When fake signals can push commercial airliners into another country’s airspace, it ceases to be a bilateral nuisance and becomes an international safety concern.
The National Security Advisor's (NSA) office launched a multi-agency cyber security investigation as hundreds of flights have experienced false terrain warnings and incorrect position data.
The Delhi–Amritsar sector and other northern routes, the sky has become less predictable. A navigation display that once inspired confidence now requires constant cross-checking. The recent Air India incident was a reminder that even routine flights can suddenly become geopolitical events when the signals from space are no longer trustworthy.
Aviation has always been an unforgiving domain. When the very signals that guide aircraft are weaponised, the margin between a routine arrival and an international incident narrows dramatically. India’s civil aviation authorities, working with the armed forces and technical agencies, are now racing to widen that margin again before another flight finds itself where it was never meant to be.
