In a world increasingly shaped by technological advancement, ensuring gender equality in STEM (Science, Technology, Engineering, and Mathematics) is no longer a choice—it’s a necessity. Recognizing this, the Indian Institute of Technology (IIT) Delhi launched a pioneering initiative titled ‘Manasvi’ , a STEM mentorship programme for high school girls . The programme, unveiled in New Delhi today, is spearheaded by the institute’s Academic Outreach and New Initiatives Office . Manasvi is not merely an educational engagement; it is a transformative platform aimed at inspiring and empowering young girls to pursue careers in STEM, fields traditionally dominated by men. At the heart of Manasvi lies the ambition to address the deep-rooted gender disparity in STEM education and careers . Despite producing the largest number of science graduates globally, India continues to see disproportionately low female representation in STEM careers —a statistic that underscores the urgent need for su...
In a concerning revelation, the Indian government recently reported 465 cases of Global Positioning System (GPS) interference and spoofing in the country’s border regions between November 2023 and February 2025. Most of these incidents have been recorded near Amritsar and Jammu, raising significant safety concerns for the aviation sector. With GPS spoofing posing serious threats to aircraft navigation and passenger safety, understanding this phenomenon and implementing robust countermeasures is crucial.
What is GPS Spoofing?
GPS spoofing, also known as GNSS spoofing, involves manipulating the signals from navigation satellites to mislead receivers into believing false location data. This malicious activity can cause aircraft to deviate from their intended flight path, potentially leading to hazardous situations. In aviation, GPS spoofing is particularly dangerous as modern aircraft heavily rely on GNSS for navigation and positioning.
Recent Incidents in India
Minister of State for Civil Aviation Murlidhar Mohol recently addressed the Lok Sabha regarding GPS spoofing incidents, confirming that several airlines reported experiencing GPS/GNSS interference near Amritsar. Such interference can disrupt communication between satellites and aircraft, resulting in pilots receiving inaccurate navigation data.
Why is GPS Spoofing Dangerous?
Loss of Navigational Accuracy: Aircraft may receive false positional data, leading to course deviations.
Communication Disruptions: Loss of connection between satellites and aircraft can impair situational awareness.
Security Threats: Spoofing incidents in border areas raise concerns about possible hostile interventions.
Operational Challenges: Pilots must quickly adapt to manual navigation, which can increase workload and risk.
Government and Airline Responses
The Indian government has issued Notices to Airmen (NOTAMs) for affected areas to alert pilots about potential GPS interference. Airlines have also implemented standard operating procedures (SOPs) to mitigate risks associated with spoofing incidents. Retaining ground-based navigation infrastructure, such as Instrument Landing Systems (ILS) and VOR stations, has been prioritized to maintain safe flight operations when GPS signals are compromised.
How Airlines are Coping with the Challenge
Airlines operating in spoofing-prone regions are now focusing on a multi-layered strategy to enhance navigational safety. Key measures include:
Increased Pilot Training: Emphasis on manual navigation techniques and contingency planning.
Technology Upgrades: Incorporation of anti-spoofing algorithms and signal authentication methods.
Coordination with Authorities: Close communication with air traffic control (ATC) and defense agencies to address disruptions promptly.
GPS Spoofing Detection Techniques
To tackle GPS spoofing, airlines and defense organizations use various detection methods, including:
Signal Quality Monitoring: Identifying discrepancies in signal strength and quality.
Multi-Frequency GNSS Receivers: Utilizing signals from multiple satellites to cross-verify data.
Cryptographic Authentication: Ensuring the integrity of satellite signals through secure coding.
How Pilots Respond to GPS Spoofing
When pilots encounter suspected GPS spoofing, they follow specific protocols to ensure safety, including:
Switching to Ground-Based Navigation: Utilizing ILS, VOR, and NDB systems.
Immediate Reporting: Informing ATC of interference to facilitate coordinated responses.
Manual Flight Adjustments: Reverting to manual navigation when necessary.
The Role of International Aviation Bodies
Organizations like the International Civil Aviation Organization (ICAO) are working on setting global standards to mitigate GPS spoofing risks. Collaborative efforts between countries aim to strengthen cybersecurity measures in satellite navigation systems.
Conclusion
GPS spoofing remains a critical challenge for modern aviation, especially in sensitive border regions. Proactive government measures, advanced technology adoption, and enhanced pilot training are essential to counter this growing threat. As incidents continue to be reported, the aviation industry must remain vigilant and adaptive to new forms of interference.
