Can vehicle-mounted GPS signal jammers effectively prevent tracking and positioning?
In order to prevent others from secretly
installing positioning devices on their vehicles, thereby revealing personal
privacy or revealing their whereabouts, some customers order some common GPS
signal jammers from the Internet and want to install them on their cars. I
think that after taking such a move, I can protect myself. Unfortunately, if
you are not familiar with the working principle of the device, you just buy a
GPS signal jammer, which often backfires. After a period of time, you find that
your whereabouts are still being controlled by others. Why is this? Can car GPS
signal jammers effectively prevent tracking and positioning?
This has to be analyzed from two aspects:
the first is to understand what type of positioning device is installed on your
vehicle. Of course, as the person concerned, he must not know where others will
install the locator on the vehicle, so naturally he cannot know what type of
positioning device it is. We can only take into account all the positioning
methods that the positioning device can take. The reason why the positioning
device can realize the positioning function and send the position information
to the remote receiving terminal will use at least two signal types. The first
type is GPS positioning signal. The GPS positioning referred to here is just a
general term. It not only includes the United States GPS satellite positioning
signals, including at least China's Beidou satellite signals, Russia's GLONASS
satellite navigation signals, European Galileo satellite signals, and so on.
The second type is data transmission signals. Data transmission usually adopts
the built-in mobile phone SIM card, and uses the mobile phone's 3G, 4G or 5G
network signal to receive and send data to the receiving end. At the same time,
the use of mobile phone SIM cards can also take into account non-precise
positioning in a rough range, which is mainly achieved through mobile phone
base stations. Compared with GPS positioning signals, its positioning accuracy
is much worse.
On the other hand, or to realize that the
vehicle-mounted GPS signal jammer can effectively prevent tracking and
positioning, it is necessary to carefully check the specific technical
indicators and functional parameters of the device when purchasing a
vehicle-mounted GPS signal jammer. For the sake of low price, some customers
choose devices that only have GPS signal interference, ignoring the
interference that should be aimed at both mobile phone positioning and mobile
phone data transmission signals. This is the real reason why some
vehicle-mounted GPS signal jammers are obviously working all the time, but they
still cannot effectively prevent others from tracking and positioning.
Even if the above two aspects are well
considered, there is still an important matter that users must pay attention to
seriously: if it is necessary to prevent tracking and positioning uninterrupted
throughout the whole process, then it is necessary to ensure continuous power
supply and continuous switching work of the car GPS signal jammer, any time It
cannot be turned off during the period. Since the positioning equipment
concealedly installed in the car is always working, once the vehicle-mounted
GPS signal jammer cannot transmit interference signals due to abnormal power
supply, even a short gap time may still cause the leakage of positioning
information.
