Premo – 3D Electromagnetic Motion Tracking Technology

Electromagnetic motion tracking system works by using low frequency isotropic magnetic field generators (3D emitter) and one or several isotropic 3D magnetic sensors.

Both the emitter and receiver sides need special 3D magnetic coilsto generate and receive the magnetic field signals.

The system sensors picks up the EMF level produced by the transmitter, which is then processed by the unique hardware. Then, the algorithms calculate a true, high precision, absolute position and orientation of the transmitter and receivers with respect to each other.

AmfiTrackis an EMF-tracking state of the art system implementation by the Amfitech company. PREMO is an expert in 3DCoildesign and manufacturing. Their expertise was built up in the automotive industry

(>30M pcs / year, 20 years of experience, 54% market share). 3D Magnetic sensors are based on 3DCoil technologies. They are key elements in the EMF Tracking System.
