  • Precise inter-tracker synchronization
  • Retransmission of data while suffering of wireless outages
  • Intuitive Windows software for real-time view, easy logging and export
  • SDK with example code facilitating real-time access to all levels of component data
  • Easy synchronization with other systems
  • Use anywhere: outside, in the office, no lab or simulated environment required
  • Fast click-in of MTw into the specially designed body straps
  • Ideal for research projects, product integration and Human-Robot Interaction


Design highlights


Click-in straps

The MTw trackers click easily into the special designed body straps. Ensuring minimal subject preparation time.


Blinking LED

The LED blinks in sync with the LED of the Awinda Master (Station or Dongle) giving the users the visual feedback that its synchronized.


No buttons

The MTw’s are operated without the use of buttons. While not using them, they will go into a power-saving sleep mode automatically

The Awinda Station is able to send or accept synchronization signals to sync with other data acquisition systems. The synchronization signals are fully configurable within MVN Studio Pro.

  • 2 BNC ports for sync-in (Slave mode)
  • 2 BNC ports for sync-out (Master mode)
  • Industry standard 3.3V TTL pulses



Xsens MT Software SuiteMT Software Suite

The MTw Development Kit includes the MT Software Suite containing:

MT Manager Software

An easy-to-use graphical user interface allowing real-time view of 3D orientation and sensor data, recording of data streamed from the MTw’s through the Awinda Station and export to ASCII files for further analysis.


Software Development Kit

The SDK gives direct and real-time access to the output of the MTw motion trackers, allowing users to configure and easily integrate the MTw’s in their own applications.

It includes drivers for various operating systems, documentation and various other useful tools. Communication is made easy with the Xsens Device API (XDA) which is completely in C-code. The MT SDK includes the following development tools:

  • C++ wrapper
  • Examples for C, C++ and Matlab.
  • Supported operating systems: Windows and Linux.
  • DLL for both 32-bit and 64-bit systems.
  • Extensive documentation on the MTw, the XBus protocol and the SDK (PDF and HTML)
