Can you really achieve anti-location tracking by using a car GPS signal jammer?

  • 2022-08-25

We often receive such inquiries: For some reason, we need to prevent the vehicle from being positioned and tracked, so we want to purchase a car GPS signal jammer and ask us if we have a suitable product that meets such requirements. Our answer is: Of course we have such products, but customers must pay attention to several precautions in the process of product selection and use:

1. It is necessary to know that the vehicle is positioned and tracked. There must be a hidden positioning device installed on the vehicle. This positioning device, in addition to using the most GPS positioning signals, may also use a mobile phone SIM card or WIFI signal for auxiliary positioning. The reality is that the customer cannot judge which positioning signal the positioning device uses, so when choosing a car GPS signal jammer, the frequency band signal that needs to be interfered is not only the frequency band of the GPS signal. The frequency band signals of the mobile phone standard are taken into account together, and effective interference is carried out.

2. Even if a suitable car GPS signal jammer is selected, in the process of use, it must be ensured that the power supply to the jamming device can be continued without interruption for a moment, so that the GPS signal jammer can continue to interfere with the signal to be effective. Prevent positioning and tracking signals from being acquired by the remote end. If the power supply is interrupted on the way, even if it is an occasional short-term interruption, it is very likely that the vehicle's positioning information will be transmitted, thus losing the role of anti-location tracking.

3. The interference ability of the vehicle GPS signal jammer for GPS signals usually has a large enough interference range. As long as the interference device is in normal working state, its interference performance does not need to be worried. However, if it is based on the method of using the mobile phone SIM card to locate, because the interference ability of the signal jammer to the mobile phone signal will be affected by the strength of the mobile phone signal, so during the driving process of the vehicle, it may be passing by or close to the base station. At times, the interference ability of the mobile phone SIM card is not good, and it may not guarantee 100% effective interference.

4. Once the vehicle GPS signal jammer interferes with the GPS signal, the remote end will definitely lose the precise positioning of the vehicle. Even if the mobile phone SIM card in the concealed positioning device successfully sends a positioning signal to the remote end, this positioning signal is only a rough positioning, and the positioning accuracy can only be achieved within a few hundred meters, and the mobile phone SIM card positioning cannot be achieved. Precisely positioned.
