The introduction of tracking technology, GPS trackers, and fleet management software has changed vehicle management in various ways. For example, due to the GPS system, the ability to track drivers, determine their driving speed, and track their route has never been so simple. With the vehicle tracker running global positioning software, team managers can simplify their work and improve driver safety by integrating Google Maps into the navigation system. With the advancement of this technology, fleet tracking and asset tracking have become more convenient, and their use is also increasing. However, certain devices (such as signal interceptors) can block GPS signals and hinder the operation of car GPS trackers, which is crucial for real-time monitoring of fleets. Signal interceptors pose a security issue to any fleet owner, and business owners must address the threat to ensure safe operation. Let's have a detailed understanding of signal blocking technology, its operation process, the legality of using signal blocking technology, and how to ensure that signal blocking devices do not interfere with GPS monitoring equipment!
GPS signal interceptors are small and compact devices used to block tracking, transmitting radio frequency (RF) signals to interfere with GPS devices such as Wi Fi signals, mobile phones, and car GPS trackers. The GPS interceptor has a small size and low power, and is only used as a shielding device when needed. In addition, there are various types of GPS jammers, such as remote jammers and drone jammers. They will block GPS signals from mobile phones, vehicle trackers, and even spy cameras.
GPS jammers can block signals from vehicles by transmitting a radio frequency that is consistent with the frequency of the car GPS tracker. This can cause signal interference, which means that the GPS tracker in the car cannot determine its position.
To fully understand the working mode of GPS jammers, it is first necessary to understand the working mode of GPS trackers. The functions of each GPS device are similar, using trilateral measurement technology to determine the position, speed, and height of objects. GPS devices use complex technology to communicate with satellites to convey location and the date and time transmitted by their GPS devices. Through GPS satellites, GPS devices calculate the duration and distance of signal transmission from the device to the satellite, in order to identify the precise position of the object. A typical GPS tracker utilizes information from four to five satellites to create precise real-time navigation or positioning.
The GPS signal jammer works by interfering with the signal transmission from satellites to GPS devices. The signal jammer generates interference patterns by transmitting signals similar to GPS devices, but with a smaller range and higher power. The result is that noise blocks the transmission path connecting GPS or GS M networks (such as 3G, 2G, and 4G). These networks are typically the targets of mobile phone jammers. However, the desktop and wifi jammers use the same method to turn off Bluetooth and Wi Fi signals.
