Military gps signal scramblers

GPS equipment will 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, and the jammer uses wireless electromagnetic waves to interfere with the communication between the card and the communication base station to achieve The purpose of GPS location cannot be queried by the user.

The working principle of GPS jammer: mainly by releasing radio interference waves, the GPS locator can be disabled within the specified electromagnetic wave band, forming the same electromagnetic environment as the equipment to achieve the purpose of blocking the signal.

There are two ways to shield GPS signals. First: the direct is to remove the two wires of the GPS host. Second: Go to the electronics market to buy a GPS signal jammer, but you must first distinguish what signal tracking method the GPS on your car uses. There are only two ways of signal tracking, (1) mobile phone signal. (2) Direct satellite tracking signal. Generally, most GPS tracking signals use mobile phone signals. GPS jammers have the same interference effect on car navigation. GPS used for car navigation is the same as mobile phone signals. It is easily interfered by electronic devices. The signals are shielded, so that all communication devices in the range lose their signals. However, such equipment also has disadvantages for the users. The signal jammer can only be turned on temporarily, and it is impossible to open it forever. As long as he turns off the jammer, the GPS will have a signal again.
