Do signal jammers block GPS?

Cedric ROCHA 2023/01/06

  The GPS receiver relies on low-power microwave signals broadcast by GPS satellites.The signal jammer generates "noise" by submerging these satellite signals with higher power but shorter distance radio signals, thus inducing the GPS tracking system to think that the GPS signal is unavailable.This is also called "cheating".

  The widespread adoption of automated fleet management and global positioning system (GPS) tracking solutions has helped companies simplify operations, improve driver safety and improve compliance with compliance regulations.If the driver using the mobile route planning application tries to block the GPS tracker through the jammer, the vehicle will not disappear; It will still appear on the real-time map as a missing journey.Although drivers may think that the jammer will make them invisible, in fact, their furtive behavior on the road will attract more attention.

  The most common is that the GPS interceptor works in a short distance and is small enough to be plugged into a power source such as a cigarette lighter or iPhone, and prevents signals from being transmitted to the GPS tracker installed in the vehicle's cockpit.Depending on the strength of the GPS interceptor, it can cover several miles or yards of GPS reception.As a result, the GPS receiver cannot receive satellite signals.The GPS jamming device is plugged into the vehicle's cigarette lighter port and works by broadcasting noise at the same frequency used by satellites.

  If field service representatives try to use GPS jammers to manipulate their position data and prevent GPS tracking, management will know.Since the devices that can shield GPS come from multiple manufacturers, their shapes, sizes and dimensions vary greatly, so it is difficult to find them in the driver's car.If the vehicle is stolen, the GPS jammer will make it more difficult for the law enforcement department to locate the vehicle, thus affecting the company's scheduling lineup.If the lost vehicle cannot be found, it may also affect the company's bottom line.This is why fleet owners should pay special attention to any modifications made to their vehicles by drivers.

  In addition, when the driver inserts the jammer into the cigarette lighter port during the journey, you will see a line at the beginning of the interference.Commercial fleet owners and operators have seen the industry shift towards technology integration across each system.However, devices known as GPS jammers and mobile phone jammers will interfere with the functions of GPS tracking devices, which are critical to real-time fleet vehicle tracking systems and pose problems for fleet owners who are trying to maintain fleet tracking and control.Occasional satellite failures may damage these signals, but the more intentional cause is GPS interference.
