  • An alternating current low frequency magnetic field digitizer, consisting of an electronic unit, a magnetic transmitter and a small receiver (pointer) fitted with a switch
  • Provides 6-degree-of-freedom: Y Z Cartesian coordinates and azimuth, elevation as well as roll orientation of the receiver
  • In combination with appropriate analysis software, 3D plant architecture can be generated in a semi-automated way.


  • Assessing and analyzing 3D plant architecture
  • Any measures where 3D coordinates are needed
  • Motion tracking
