1. What is a GPS Jammer?
The GPS signal jamming system is designed to suppress signals from global satellite navigation GPS systems in the 1500-1600 MHz range. The jammer makes it impossible for GPS satellites to monitor the location of the car and all vehicles via GPS, and the gps blocker 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. Immediately after initiating the connection via the cigarette lighter gps jammer, the device starts working and generates radio noise (interference) in the 1500-1600 MHz (L1/L2) range within a 15m radius.
Second, 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.
Three, car GPS jammer
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.
Fourth, the working principle of GPS jammer:
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: go to the electronics market to buy a GPS signal jammer., but first of all, you need to know what kind of 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 of the GPS tracking signals use mobile phone signals. The signal is blocked, so that all communication equipment within the range loses the signal. However, such a device also has drawbacks for the user who uses it. The signal jammer can only be turned on temporarily, and cannot be used forever. As long as he turns off the jammer, the GPS signal will be available again.
