When it comes to GPS signal jammers, here is some more relevant information:

Functional principle: The GPS blcoker interferes with or blocks the signal of the GPS receiver by emitting wireless signals of specific frequencies. They will send powerful wireless signals to the surrounding environment, making it impossible for GPS devices to receive positioning signals from satellites, resulting in positioning failure or errors.

Device type: The look and form of a GPS signal jammer varies by manufacturer and model. They are typically portable devices similar in size and shape to a cell phone, remote control, or small box. Some GPS signal jammers also have built-in batteries to provide an independent power supply.

Frequency range: GPS signal jammers are typically capable of jamming specific frequency ranges, including GPS signals on the L1 band (1575.42 MHz). Some advanced devices can also interfere with signals on the L2 band (1227.60 MHz) and L5 band (1176.45 MHz).

Legality: In most countries, it is illegal to use, sell or manufacture GPS signal jammers illegally. This is because blocking GPS signals can pose serious threats to public safety and critical infrastructure. However, there may be a need for legitimate use of GPS signal jammers in certain specific situations, such as military, law enforcement, or safety testing.

Risks and Limitations: Illegal use of a signal jammer may result in serious consequences. This may include transportation system chaos, emergency rescue obstruction, positioning errors, infrastructure failures, etc. In addition, illegal use of GPS signal jammers may also face legal liability and severe penalties.
