An electromagnetic tracking system is a system that tracks an object in a three-dimensional space using electromagnets. It is also called a magnetic tracking system. Examples are the Polhemus Viper and the NDI Aurora.
Electromagnetic tracking systems typically use three coils for the X, Y, and Z directions. There is a base station and a receiver. The base station generates the magnetic field, and the receiver senses it.
Electromagnetic tracking systems must be calibrated before they can be used.
Magnetic tracking systems are typically expensive.
Examples
Construction
There must be an analog to digital converter (ADC), magnet wire (enameled wire), and a microcontroller.
