Of course, there are other situations. For example, for some reason, you don’t want your vehicle to be located by others and master the driving route. At this time, you can also use gps jammer to maintain privacy. The working principle of the GPS signal jammer is to cut off the GPS frequency band signal, so that the car is in a signal isolation state. The 2-antenna GPS jammer has the following characteristics: 1. Effectively interfere with GPS and Beidou satellite signals to protect your track privacy and information confidentiality. 2. Small size, high power, light weight, large coverage area, easy to carry; 3. Only GPS and Beidou signals are shielded, and it does not affect the connection and calling of mobile phones. Of course, the 6-antenna, 8-antenna, and 9-antenna GPS jammers are more powerful. In addition to shielding GPS and Beidou signals, they can also shield 2G3G4G and wifi signals, completely block wireless signals, and better protect driving privacy.
GPS signal detector can be used to detect GPS locator. It can detect whether there is a locator installed in your car by receiving frequency, but this kind of signal detector can only be used for wired GPS, because wired GPS sends out more frequently every day. It can be easily captured and positioned by the signal detector. But if the car is equipped with a wireless GPS, it only sends the frequency once a day, and the time is particularly short, then the signal detector cannot catch it in this case. You can find a company that specializes in testing GPS locators. Of course, people need to interfere with the GPS to ensure that their equipment is always working. However, it is ironic that GPS jammer devices can also potentially compromise personal safety, just as it causes safety. If terrorists can obtain important location information of government property, or even if the wife tries to catch her cheating husband, GPS signals can also be useful to disturb things.
