PST Base Specifications


  • Accuracy: Position: < 0.5 mm RMSE
    Orientation: < 1 deg RMSE
  • Latency:15-25 ms (depending on the shutter time and the filter settings)
  • Tracking distance:20 cm up to 3 m
  • Field of view:60° (horizontal), 45° (vertical)
  • Refresh rate:120 Hz, adjustable to 30, 60, 120 Hz

Devices and Markers

  • Number of targets:At least 15 independent 6DoF bodies. For instance: simultaneous head and object tracking
  • Markers:Passive (retro-reflective flat and spherical) – Active (LED)
  • Device creation:Simple procedure: mark, train and use new device in seconds


  • Processing:An additional processing unit is in most cases not needed. Extra processing power (e.g. with a NUC) is recommended for a multi PST setup or networked access
  • Tracking application:PST Software Suite 5 (license included with each PST tracker)
  • Client operating system:Windows 7, 8 and 10 (32 and 64 bit)
  • Software interface:The tracker comes with an easy to use native C/C++ SDK and bindings for C# and Python. Interfacing is also supported via VRPN, trackd1, Dtrack emulation, data export to .CSV
  • Hardware interface:USB 2.0 (ethernet connection to the PST available through the PST Software Suite 5)
  • Output:Positional coordinates (x, y, z), orientation angles, Euclidean transformation matrix
  • Synchronization:Hardware trigger in and out
