GPS Spoofing
Context
India sent military aircraft to Myanmar to deliver earthquake relief materials under Operation Brahma. While flying over Myanmar, some Indian Air Force (IAF) aircraft faced GPS spoofing — a type of cyberattack that sends false GPS signals to confuse aircraft about their actual location.
What is GPS Spoofing?
- GPS spoofing refers to an attempt or a cybersecurity threat to alter the initial location of a GPS-enabled device.
- GPS spoofing sends false data to a receiver to divert traffic, goods, or people with falsified information.
- How is it done?GPS spoofing involves a radio transmitter near a target that interferes with the actual GPS signals being transmitted.
- GPS signals are often weak and transmitted through satellites.
- A stronger radio transmitter can be used to override the weaker signal and send illegitimate coordinates and information to the receiver.
- GPS spoofing can then send people off course or say that someone is somewhere that they are not.
- Types of Spoofing: Spoofers overpower relatively weak GNSS signals with radio signals carrying false positioning information. There are two ways of spoofing:
- Rebroadcasting GNSS signals recorded at another place or time (so-called meaconing)
- Generating and transmitting modified satellite signals
