What are the devices that interfere with positioning navigation?

1. Electromagnetic interference equipment
Electromagnetic interference equipment refers to equipment that can deliberately or accidentally release electromagnetic waves to interfere with the normal work of various electronic equipment. For car navigation and other positioning equipment, electromagnetic interference can cause problems such as loss of signal, increasing error, decreased accuracy, and even directly affecting the use of the vehicle navigation system.  signal jammer
2. GPS jammer 
The GPS jeopher mainly simulates or covers satellite signals by sending a weak radio signal transmitter to interfere with the normal operation of the GPS receiver. During navigation, the GPS jammer can affect the accuracy of the device, allowing users to have deviations in places where high -precision navigation is required by highways, resulting in hidden dangers of driving safety.
3. iron oxygen magnetic ring
The magnetic ring is a special material that can change the magnetic field of the car navigation equipment by adjusting the current, thereby interfere with the positioning and navigation treatment. The iron oxygen magnetic ring is often used to monitor, locate and block the frequency of communication.
Fourth, microwave interference
Microwave interference is a device that can disrupt wireless communication signals by high -frequency electromagnetic waves. It can affect the receiving and processing of vehicle navigation equipment signals, which leads to inaccurate positioning.
