Measures to Avoid Tracking and Positioning with a Car GPS Jammer

perfectjammer png2022/08/17

Some customers are concerned that they may be tracked and located for privacy or confidentiality reasons, so they buy a car GPS signal jammer and install it in the car they use to get around. But when using these car GPS signal blockers, can the GPS signal be effectively blocked?

Precautions for car GPS jammer to prevent tracking and positioning

Can it really prevent tracking and positioning?

In fact, the most widely used car GPS signal blocker on the market is relatively small, and if it is directly plugged into the car cigarette lighter, the GPS signal will be blocked. This GPS jammers looks simple and convenient, but it's not really effective at preventing tracking and positioning.

There are several limitations when using this GPS jammer:

  1. GPS signal jammers can only be effective for GPS trackers.
  2. If the tracker installed on the car uses not only GPS positioning chips, but also mobile phone SIM cards or other positioning chips, only such a small GPS signal jammer is not effective to prevent its tracking location.
  3. Although the GPS positioning information is blocked, the positioning information of the car is still transmitted to the outside world in the form of mobile phone data through the SIM card of the mobile phone;
  4. It must be ensured that the connection of the cigarette lighter socket is reliable. Since the GPS signal jammer is powered through the cigarette lighter socket, if the socket connection is loose and the power is cut off, the GPS signal jammer's work will be interrupted, and it is easy to leak location information again;
  5. It is necessary to keep the vehicle started or not stop the engine halfway. When the GPS jammer is turned on, even if the vehicle is temporarily parked or stationary, do not rashly turn off the ignition or turn off the power of the cigarette lighter, otherwise the location information of the vehicle will be leaked quickly;

Using a car GPS signal jammer to prevent tracking and positioning raises several concerns and limitations that users should be aware of. While these devices may seem convenient and offer a semblance of privacy protection, their effectiveness in blocking GPS signals and preventing tracking is limited by various factors.

Prevent Call in Prison

One of the primary limitations of car GPS signal jammers is their inability to block all forms of tracking technology. Most GPS jammers available on the market are designed to specifically target GPS signals, but they may not effectively block other tracking methods employed by modern tracking devices. For instance, if a tracker installed on the vehicle utilizes not only GPS positioning but also mobile phone SIM cards or alternative positioning chips, the GPS jammer alone may not be sufficient to prevent tracking. In such cases, the tracker may still transmit location information through alternate means, rendering the jammer ineffective.

The real problem is the price of GPS jammers

Additionally, the reliability of power supply to the GPS jammer is crucial for its continuous operation. Since these devices are typically powered through the car's cigarette lighter socket, any disruptions or fluctuations in power supply could lead to the jammer malfunctioning or being deactivated. Loose connections or interruptions in power supply may result in the jammer failing to block GPS signals effectively, thereby compromising the user's privacy.

Moreover, the proper usage of the GPS jammer requires that the vehicle's engine remains running or the ignition is not turned off abruptly. If the jammer is activated while the vehicle is stationary or parked, users must ensure that the engine remains running to sustain power supply to the jammer. Abruptly turning off the ignition or disconnecting power to the cigarette lighter socket can lead to the jammer being deactivated, potentially allowing location information to be transmitted once again.

while car GPS signal jammers offer a measure of privacy protection against GPS tracking, their effectiveness is subject to various limitations and considerations. Users should carefully assess their specific tracking concerns and understand the capabilities and limitations of GPS jamming technology before relying solely on these devices for privacy protection. Additionally, it's important to stay informed about relevant laws and regulations regarding the use of GPS signal jammers in vehicles to avoid potential legal consequences.
