The MTi is a miniature, gyro-enhanced Attitude and Heading Reference System (AHRS). Its internal low-power signal processor provides drift-free 3D orientation as well as calibrated 3D acceleration, 3D rate of turn and 3D earth-magnetic field data.

The MTi is an excellent measurement unit (IMU) for stabilization and control of cameras, robots, vehicles and other (un)manned equipment.

The standard MTi version contains accelerometers with a full scale of 5g and gyroscopes with a full scale of 300°/s. Optional are accelerometers with a full scale of 18g, and gyroscopes with a full scale of 150°/s and 1200°/s (for more information view "specs" section).

A number of pre-set user scenarios are available optimizing the Extended Kalman Filter routine for different applications. These pre-set user scenarios replace the manual filter settings used in previous versions of the Xsens sensor fusion algorithm . Based on the chosen scenario the sensor fusion algorithm will apply optimised filter settings recommended for the application.

MT Development Kit

First-time users should acquire the MTi Development Kit. This kit includes an MTi measurement unit, a calibration certificate, a user manual, a RS232 (USB Cable) and our user friendly MT Software Development Kit (SDK). The Development Kit allows users to fully explore the possibilities of the MTi, and the integration possibilities of the MT with your own system. With the Development Kit you have will have your measurement unit up and running in just a few minutes to start your first R&D.

Compact Design

  • Compact and robust design
  • Easy integration in any system (OEM) application
  • Low weight, ultra-low power consumption

High Performance

The MTi uses inertial sensors in order to estimate the orientation. The gyroscopes are used to calculate orientation. Integration drift is inevitable whilst using gyroscopes. To compensate for drift completely, the MTi corrects its orientation every sample using the gravity and the earth magnetic field as reference vectors.The sophisticated Xsens sensor fusion algorithm can cope with short-term magnetic disturbances and lateral accelerations, resulting in a reliable orientation estimate. Additionally, the MTi incorporates a magnetic field mapping routine to correct for hard and soft iron effects.

User scenarios

The MTi is a sensor which can be used in a wide range of applications. To accommodate application specific requirements, the fusion algorithm supports different filter settings and constraints, implemented in scenarios.

Output

  • 3D Orientation (360°)
