What is a GPS jamming device?

GPS signal jammers are small, high power radio frequency (RF signal) transmitters that interfere with lawful communications devices—cell phones, GPS, Wi-Fi networks and also toll readers. How do GPS jamming devices work? GPS receivers rely on low power microwave signals broadcast from GPS satellites.

What is coherent jamming?

Coherent jamming is proposed for jamming ISAR. Some video signals modulate the receiving signal in frequency domain, then the resulting signal is retransmitted. The dechirped output of the coherent jamming will produce cover jamming. Thus, ISAR can not obtain the range image.

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.
