GPS jammer prevents satellite positioning and tracking

As GPS systems become more and more popular, GPS signal jammers are becoming more and more necessary for us. You may want to know what GPS Jammers are and what potential applications they have. To explain the GPS jammer, we first need to understand the working principle of the GPS system. Global Positioning System --- GPS for short, is a system used by many people, companies and military for navigation purposes. The GPS system uses a series of satellites that emit radio signals. This type of signal reaches an electronic GPS receiver to determine the position by triangulating the shape. GPS can be used in personal portable electronic devices, vehicle navigation and positioning systems, and can also be used in small GPS tracking devices. The position of a person can be found by triangulation, which is a method of measuring three separate points to calculate the position. In the GPS system of a vehicle, a car is measured by three satellites orbiting the earth. GPS can transmit position information to the receiver through triangulation, and the accuracy is only a few inches.

Now let’s take a look at a very useful GPS jammer: a 40-meter handheld GPS jammer, model EO04201FR. This 40-meter portable GPS GPS jammer can effectively prevent GPS satellite positioning and tracking! It can also be used as an effective interference to GPS satellite signals to protect your privacy without affecting the normal telephone response. The large-capacity portable built-in lithium battery can be used for five hours. This may be useful even if the vehicle is not started using the same Power source. Small size, Powerful charger, light weight and large coverage, the device is easy to install and use, and can be carried with you. Most importantly, it is really cheap,
