Recent reports have emerged of the Global Positioning System (GPS) on aircraft being intentionally jammed or spoofed while flying over certain airspaces in the Middle East region. This has resulted in planes veering dangerously off course or flying blind without navigation capability. Responding to the threat, India’s aviation regulator, the Directorate General of Civil Aviation (DGCA), has released an advisory circular for airlines and airports on tackling the GPS interference through robust mitigation measures.
What is GPS Jamming and Spoofing?
Jamming refers to blocking real GPS signals to aircraft by transmitting disruptive radio frequency noise from the ground. Spoofing means a false GPS signal is sent to manipulate and trick the aircraft’s navigation system into displaying an incorrect position, making the plane go off its route. Together, jamming and spoofing can severely compromise flight safety if pilots are unaware and lack contingency procedures when critical systems fail.

Recent Incidents and Areas Impacted
According to the DGCA’s circular, there have been rising reports of GPS jamming and spoofing in Middle East airspace impacting civilian flights. One notable case last September saw a plane nearly veer into Iranian territory when its navigation was disrupted. The primary areas currently facing regular GPS interference are Northern Iraq flight routes near Erbil and Turkey airspace adjoining Iran border.
As per estimates, over 12 incidents have occurred near Erbil just this year, indicating the growing scale of this threat. Aviation experts speculate the disruptions may be from sophisticated military electronic warfare systems activated in volatile regional geopolitical zones.

Comprehensive Mitigation Measures
Identifying the serious nature of the problem, the DGCA has laid out detailed guidelines for airlines to coordinate with aircraft manufacturers in conducting safety risk assessments of routes and developing alternative contingency plans when critical navigation infrastructure is unavailable. This includes procedures enabling pilots to safely fly and land using alternative means if satellite navigation is denied for prolonged durations.
Furthermore, in conjunction with the Airports Authority of India (AAI), efforts will be made to institute a live threat monitoring system that can analyze reports of GPS jamming to rapidly disseminate information for evasive response.

Conclusion
The emerging trend of intentional interference with aircraft GPS signals across high-sensitivity regions has necessitated urgent action from aviation bodies. By preemptively addressing this through updated procedures, alternative navigation infrastructure, active tracking of jamming sources and close industry coordination, the DGCA hopes to counter a dangerous risk to passenger safety with an efficient mitigation strategy before any major incident.
As flights increasingly rely on GPS networks for fundamental operations, maintaining resilience against jamming and spoofing will be pivotal. The regulator has provided the framework, but sustained efforts from airports and airlines will determine how effectively this threat can be tackled.
