MTw Development Kit Lite (legacy product)

Wireless motion tracker

Important: Read the End-of-Life notice

The MTw Development Kit Lite is an solution for applications where orientation is required via a wireless connection. It is highly suitable for markets like training & simulation, pedestrian navigation, test & measurement and robotics.

  • Completely wireless
  • Long battery life of up to 4 hours
  • Accurate data


Important: End-of-Life

On October 29, 2015, Xsens has issued an End-of-Life (EoL) notice for the 1st generation of MTw products. Details on the EoL can be found in the End of Life Notice MTw 1st generation (PDF). Please refer to the new MTw Awinda for the 2nd generation MTw.


  • Autonomous Indoor Positioning and Navigation with an Inertial Measurement UnitCompletely wireless
  • Long battery life of up to 4 hours
  • Compatible with software for MTi 10-series and MTi 100-series
  • Intuitive Windows software for real-time view, logging and export
  • Extensive SDK with example code for system integration
  • Accurate data
  • Highly sensitive MEMS inertial sensors
  • Internal sampling at 1800 Hz and internal pre-processing maintains accuracy under challenging dynamic conditions
  • Sensor fusion algorithms ensures highly accurate, drift-free output
  • Highly suitable for training & simulation, pedestrian navigation, test & measurement and robotics


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.
