What is magnetic navigation technology

Magnetic navigation is currently the most mature and reliable program, and most of them are now using this navigation technology. By burying certain navigation devices (such as magnetic spikes or wires) on the road and encoding them by changing the direction of the magnetic poles, it can transmit to the vehicle information about the road characteristics, such as location, direction, radius of curvature, and the location of the next road exit, thus indicating the direction for the car. For example, the Park Shuttle system at Amsterdam International Airport and Rotterdam in the Netherlands, and the Cyber C3 system at Shanghai Jiao Tong University, all use this technology, which is also used in trackless automatic retractable doors. The biggest advantage of magnetic navigation is that it is not affected by weather and other natural conditions, even if the wind and sand or snow bury the road surface is also effective. However, the implementation of this system is relatively cumbersome, and not easy to maintain, change the operating line needs to be re-buried navigation equipment.
