GPS signal jammer sends radio signals at exactly the same frequency

District of Columbia, South Carolina-South Carolina plans to disrupt cell phone signals in prisons to prevent criminals from committing further crimes. There is a major problem with this plan: it is illegal. The struggle to stop the use of mobile phones in prisons-some experts say the device has become a new form of cash-has led states to experiment with old-fashioned cell scanners, sophisticated body scanners, and even those trained to track batteries and memory chips dog. South Carolina State Warden Jon Ozmint (Jon Ozmint) hopes to complement this strategy by blocking cell signals with existing technology. The Federal Communications Act, which prevents states from using GPS Jammers or otherwise interfering with federal radio waves, is hindered.

To understand how the GPS blocker works, it will be helpful to be familiar with how GPS works. GPS stands for Global Positioning System and works through the GNSS network (Global Navigation Satellite System). The GPS tracker is connected to the GNSS network. GPS signal jammers send radio signals at exactly the same frequency as GPS devices, which overwrite the signals sent by satellites. In this case, the GPS tracking device cannot determine its exact location because the scrambler is interfering with its signal. GPS jammers can interfere with all functions of the GPS system, including navigation and tracking. GPS jammers are usually small and easy to install. It takes less than a minute to boot up and can be installed and removed carefully. They are illegal under federal law and may result in personal fines or imprisonment. Even so, GPS jammers are still common and often cheap.
