Where are GPS jammers generally used - cell phone signal jammers from dojammer's blog

1. 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 1500-1600MHz range. Jammers make it impossible for GPS satellites to monitor the location of cars and all vehicles via GPS, and gps jammer devices will not interfere with cell phones and other devices. The GPS jammer range can be from 5 to 15 meters, which is enough for cars and buses as the trackers are usually installed in the cab inside the car. After initiating the connection via the car's cigarette lighter, the device starts working immediately and generates radio noise (interference) in the range 1500-1600 MHz (L1/L2) within a radius of 15 meters.

  • The GPS positioning and navigation system only requires a GPS signal jammer.
  • Dual-mode navigation: network positioning (mobile phone signal positioning) navigation + GPS navigation. For this kind of navigation you need GSM GPS jammer.
  • Network positioning (mobile phone signal positioning) navigation. For this you need a gsm jammer.
  • 4. COMPASS system, GLONASS system and Galileo system.

GPS devices all require a phone card. The current location information calculated by the GPS module is uploaded to the positioning server by the communication base station through this card for user query. The jammer uses radio 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.
