Does the cheap gps jammer also have the function of shielding signals?

We target GPS navigation systems with a low cost jammer that effectively disrupts signals, taking into account spectral efficiency, energy efficiency and complexity. The results show that the tested method can stop receiving radio navigation signals reliably in real life scenarios.

GPS jamming devices are affordable and easy to use. They're perfect for people who care about GPS monitoring. The relatively low power and fast start time allow the jammer to be used only when needed. While not necessarily legal, it is reasonable to purchase various types of cheap GPS jammers online, such as physical shielding, Wi-Fi/ Bluetooth jammers, remote control jammers, spy camera jammers, and drone jammers.
The user plugs the jammer into the car's auxiliary power outlet. When activated, the GPS jammer produces a jamming signal within a radius of 5 to 10 meters to interfere with the reception of GPS satellite signals. Some people find that they bought a car with GPS monitoring and they don't trust it. It's hard to find and disconnect, so sometimes they buy GPS jammers to fight the monitors.
