What is a GPS jammer?

The GPS signal jamming system is designed to suppress the signals of the global satellite navigation GPS system in the range of 1500-1600MHz. The jammer makes it impossible for GPS satellites to monitor the location of cars and all vehicles through GPS, and the GPS jammer device will not interfere with mobile phones and other devices. GPS jammer can range from 5 to 15 meters, which is sufficient for cars and trucks and buses, because the tracker is usually installed in the cab inside the car. After starting the connection through the car cigarette lighter, the device immediately starts to work and generates radio noise (interference) in the range of 1500-1600 MHz (L1/L2) within a 15-meter radius.

GPS jammers have that type

1. GPS positioning and navigation system, only need gps jammer.

2. Dual-mode navigation: network positioning (mobile phone signal positioning) navigation + GPS navigation. For this kind of navigation, you need a GSM GPS jammer.

3. Network positioning (mobile phone signal positioning) navigation. For this, you need a gsm jammer.

4. COMPASS system, GLONASS system and Galileo system.

234 These three systems are hardly used for civilian purposes.

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 invalidated within the designated 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) Cell 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 the signal again.
