Where are GPS jammers generally used?
The GPS signal jamming system is designed to suppress signals from global satellite navigation GPS systems in the 1500-1600MHz range. The jammer makes it impossible for GPS satellites to monitor the location of the car and all vehicles via GPS, and the gps jammers device does not interfere with cell phones and other devices. Gps jammers can range from 5 to 15 meters, which is more than enough for cars and trucks for cars and buses, since trackers are usually installed in the cab inside the car. After initiating the connection via the car's cigarette lighter, the device started working immediately and generated radio noise in the 1500-1600 MHz (L1/L2) range within a 15m radius.

GPS devices all need a phone card. The current location information calculated by the GPS module is uploaded from the communication base station to the positioning server through this card for users to query. The jammer uses wireless electromagnetic waves to interfere with the connection between the card and the communication base station to achieve The GPS location cannot be queried by the user for the purpose.
Mainly through the release of radio interference waves, the GPS locator can be disabled within the specified electromagnetic band, forming the same electromagnetic environment as the device to achieve the purpose of blocking the signal.
Two methods of blocking GPS signals. First: directly remove the two lines of the GPS host. Second: buy a GPS signal jammer online, but you must first identify what kind of signal tracking method is used by the GPS on your car.
Generally, most of the GPS tracking signals use mobile phone signals. The signal is blocked, so that all communication equipment within the range loses the signal.
