What is a GPS jamming device?

How do GPS jamming devices work? GPS receivers rely on low power microwave signals broadcast from GPS satellites.

What is a signal jammer and how does it work?

Signal jammers operate by overwhelming these satellite signals with higher power, but shorter range, radio signals, to create “noise” that tricks GPS tracking systems into thinking GPS signals are not available. This is also referred to as "spoofing". What do GPS jammers look like?

Do GPS jammers and cell phone jammers interfere with GPS tracking?

However, devices known as GPS jammers and cell phone jammers can interfere with the function of the GPS tracking devices that are critical to real-time fleet vehicle tracking systems, and present issues for fleet owners trying to maintain fleet tracking and control.

What frequency do GPS jammers work?

Although the article said the jammer is designed to work only against civil-use GPS signals broadcast on the frequency of 1575.42 MHz and not the military frequency of 1227.6 MHz, James Hasik, an Atlanta-based consultant and author of the book The Precision Revolution: GPS and the Future of Aerial Warfare, disagreed.
