Use a car GPS signal jammer to prevent tracking and positioning

For personal privacy or confidentiality needs, some customers are worried about being tracked and positioned, so they purchased a car GPS signal jammer and installed it on their travel cars.

A jammer gps is typically a small, self-contained transmitter device used to hide its location by sending a radio signal on the same frequency as a GPS device. When this happens, the GPS device cannot determine its location due to interference.

But when using these car GPS signal blockers, can the GPS signal be effectively blocked? Can it really prevent tracking and positioning?

In fact, the most common car GPS signal jammers that can be seen on the market are relatively small in appearance. Plug it directly into the car’s cigarette lighter and the GPS signal will be blocked. This GPS signal jammer seems simple and convenient, but it does not really effectively prevent tracking and positioning. There are several considerations when using this GPS jammer:

The vehicle must be kept on or not turned off halfway. In the process of turning on the GPS signal jammer, even if the vehicle is temporarily parked or resting, do not rashly turn off the ignition or turn off the power of the cigarette lighter, because this will cause the vehicle’s positioning information to leak quickly.

Make sure that the socket connection of the cigarette lighter is reliable. Since the GPS signal jammer obtains power through the socket of the cigarette lighter, if the connection of the socket is loose and the power supply is interrupted, the work of the GPS signal jammer will be interrupted, and it is easy to expose the positioning information again.

From the power size and coverage of the device, it can be roughly divided into:

1. Low-power portable jammers generally refer to the transmit power of each RF module between 0.5-1W.

2. Medium-power portable jammer refer to jammers that transmit power between 10-20W in each radio frequency band.

3. High-power portable jammers refer to the transmit power of each module between 50-100W.

In order to ensure a better signal effect, in general, after installation, check whether the power cord of the mobile phone signal jammer is reliable and reliable, connect to the 220V mains, then turn on the power switch of the mobile phone signal jammer, and finally observe the main power supply of the mobile phone. The unit of the signal jammer. Whether the power indicator on the shell panel is normal, if the power indicator is not on, please contact the equipment supplier in time.
