Design highlights



The MTw Lite tracker clicks easily into the special designed body straps. Ensuring minimal 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 sensor has no buttons, so less chance to break.

Xsens MT Software SuiteMT Software Suite

The MT Software Suite gives easy access to Xsens’ products, allowing users to configure and easily integrate the MTw Wireless Motion Trackers in their own applications. The suite contains a specially developed and easy-to-use graphical user interface, as well as drivers for various operating systems and many other useful tools, example source code and documentation.

Although it is easy to set up the MTi via the low-level XBus protocol, 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)
