In the context of Industry 4.0, the application of positioning technology is becoming more and more widespread, especially in areas such as unmanned driving and logistics management. Although GPS technology provides accurate location services, its susceptibility to interference is also worrying. In response to this situation, GPS jammers, as a means of protection, can resist invalid location tracking and interference. By blocking the access of illegal signals, gps jammer can effectively protect data security and normal operation of equipment during transportation, ensuring the smooth progress of the logistics process.
