GPS jamming

GPS jamming near conflict zones affect cargo ships transiting Mediterranean and the Black Sea.

About GPS (Global Positioning System) jamming:

• GPS jamming, also known as GPS spoofing, is the act of using a frequency-transmitting device to disrupt or interfere with radio communications.
• Types of communications that can be jammed include phone calls, text messages, GPS systems and Wi-Fi networks.
• GPS jammers, the devices used to do the jamming, are also referred to as cellphone or signal blockers.

How does it work?

• Receivers use orbiting satellites and radio signals to pinpoint the location of GPS-enabled devices or vehicles.
• However, a jammer is a device that confuses the receiver by emitting radio signals at the same frequency as the GPS.
• This interference hampers the ability of the GPS device to determine its correct position.
