MTi (legacy product)

Miniature MEMS based AHRS

The MTi is discontinued since August 31st, 2014. Please refer to the MTi 10-series and MTi 100-series.

The 3rd generation MTi contains gyroscopes, accelerometers and magnetometers in 3D, which enables it to output drift free orientation and calibrated data in real time. It has been proven in the field with 10.000s units shipped.

  • Reliable MEMS based orientation sensor
  • Featuring Xsens Kalman filter
  • On board DSP, running sensor fusion algorithm


EOL notice


Important: End-of-Life. The MTi is Xsens 3rd generation product. On August 31st, 2013, Xsens has issued an End-of-Life notice for the 3rd generation MTi products. Details on the EOL can be found in the End of Life Notice MTi 3rd generation (PDF). Please refer to the new MTi 10-series and MTi 100-series for the 4th generation MTi.
