What is a GPS Jammer?
GPS signal blocker is the process of using frequency transmitting equipment to block or interfere with radio communications. Types of communications that may be disrupted include phone calls, text messages, GPS systems, and Wi-Fi networks. The term is also called GPS spoofing, and the device used can also be called a cell phone or signal blocker. GPS signal jammers are designed to interfere with global satellite navigation GPS system signals in the 1500-1600MHz range. The jammer makes it impossible for GPS satellites to monitor the car and the location of the vehicle through GPS, and the gps jammer device will not interfere with mobile phones and other devices. GPS jammers can range from 5 to 15 meters, which is more than enough for cars, truck mixers, and buses.
The type of the GPS jammer
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.
Three, car GPS jammer
GPS jamming device 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.
Two methods of blocking GPS signals.
First: directly remove the two lines of the GPS host;
Second: Use a GPS signal jammer, but you must first identify what kind of signal tracking method is used by the GPS on your car.
There are only two ways of signal tracking:
(1) Mobile phone signal;
(2) Direct satellite tracking signal.
Generally, most of the gps scrambler use mobile phone signals. The signal is blocked, so that all communication equipment within the range loses the signal.
