Kolkata Air Traffic Control Alerted to GPS Interference After Delhi, Mumbai
Imagine airplanes need a special GPS signal to know where they are, like a map app on your phone.
Someone is sending fake GPS signals, which is like messing with the map app.
This has been happening in India.
First, it happened near Delhi, then Mumbai, and now near Kolkata.
Air traffic controllers and pilots have been warned about this fake GPS signal.
The government is looking into who is doing this.
To make sure everyone is safe, the aviation police are asking pilots and controllers to report any fake GPS signals right away.
This is to prevent problems with flights, like the big disruption that happened in Delhi.
Kolkata received a NOTAM alerting pilots and ATC to GPS interference approximately 50 nautical miles away.
This follows similar incidents in New Delhi and Mumbai, part of a cyberattack on the Indian aviation sector.
The Directorate General of Civil Aviation (DGCA) mandated real-time reporting of GPS anomalies within 10 minutes.
The incidents are linked to alleged GPS spoofing, which deceives aircraft navigation systems with false data.
The office of the National Security Advisor is investigating the cyberattack.
