GPS jammers may interfere with vehicle speed monitors
We know that GPS jammers can interfere with GPS signals. So for some GPS trackers, GPS jammers can act as a countermeasure. This is how we use GPS jammers to protect our privacy and prevent them from being tracked.
However, GPS jammers can also be used inappropriately by unwitting users.
To avoid the company's overclocking monitoring, taxi drivers can install GPS jammers in their cars.
According to reports, when a user reported a taxi in Queens, New York, he found that when the vehicle entered the main road of the LaGuardia Airport route, the driver suddenly took out an MP3-like gadget from the storage box in the car. In the cigarette lighter, the driver tells the user that this is a GPS-Jammer, the purpose is to block the GPS signal, the company's monitoring platform can only see where the car is, but the speed is zero.
He also told users that the interference was mainly caused by the company's own speeding and escaping. Many taxi drivers have this thing. If the road conditions are good or they are running long distances, the driver will bring the signal jammer into the car. Use a signal jammer to shield the GPS tracking system, so that the GPS positioning system only displays the vehicle's position and cannot monitor the actual speed of the vehicle.
Since car GPS jammers can be very small, they can be difficult to find.
In order to detect the function of the GPS jammer, please download the GPS signal detection software to test the shielding effect, or open the car navigation function test。
