The tracking server calculates all individual distances from zacTag to each anchor and triangulates the real time position … The simplified spring model describes this method.

The technical accuracy of the system is +/- 5cm. But the actual “Accuracy” of the whole tracking system in general is influenced by the combination of three factors:

• Update rate
  The rate of positional measurements per second defines the amount of data for the prediction math. The higher the update rate, the smoother my movements.
  (typical for UWB radio tracking: 15Hz to 35 Hz)
  
  
• Error distribution
  The maximum radius and the shape of the error distribution defines the amount of filtering to achieve a stable position measurement.
  
  
• Latency
  The latency is the delay between the actual movement in the real world and the output of the calculated position over the network including the actual movement behavior of the effect device (fixture, camera,…) . Bad update rate und error distribution will increase the overall latency.
