Xsens MTI-3 AHRS Sensor Module

Xsens MTi-3 AHRS Sensor Module

The MTi-3 AHRS sensor module is the smallest self-contained Attitude Heading and Reference System (AHRS) on the market. The Xsens optimized strapdown algorithm (AttitudeEngine™) performs high-speed, dead-reckoning calculations at 1 kHz, accurately capturing high-frequency motions.



The MTi-3 AHRS sensor module is a self-contained Attitude and Heading Reference System (AHRS). In addition to the data collected and computed by the MTi-1 and the MTi-2, it delivers true North-referenced yaw, or heading.

As a member of the MTi 1-series, the MTi-3 stands out for its small form factor (12.1 mm x 12.1 mm), easy integration, low cost and robustness – as well as its strapdown integration algorithm. Suitable for a wide range of (embedded) applications, the MTi-3 relieves you of the effort of integrating and maintaining gyroscopes, accelerometers and other sensors as well as of having to design an all-in-one AHRS solution.

The MT Software Suite has everything you need to operate the MTi-3. The suite contains a specially developed, easy-to-use graphical user interface, as well as drivers for various operating systems. It also offers other useful tools and software programs, such as:

  • MT Manager (GUI)
  • MT SDK, including programming examples for C, C++, C#, MATLAB, Python, ROS and Nucleo boards
  • Magnetic Field Mapper (MFM) calibration tool, as GUI and SDK


  • Smallest form factor on the market
  • Easy integration
  • 3D models available on request
  • Development kit available
