Xsens Technologies BV Vertical Reference Unit MTi-20 VRU

The MTi 10-series is available in three integration levels: an IMU, a VRU and an AHRS. The 10-IMU offers sensor data, also available as delta_q and delta_vel. It is an excellent unit for designing own fusion filter algorithms, using the MTi’s excellent signal processing pipeline. The 20-VRU offers gravity referenced roll and pitch and unreferenced heading on top of the sensor data of the MTi. The 30-AHRS is a full 3D AHRS, also providing magnetic-referenced heading. Signal processing pipeline All products from the MTi 10-series feature the same state-of-the-art signal processing pipeline with a high bandwidth of 375 Hz for the accelerometers and 415 Hz for the gyroscopes. Oversampling at 10 kHz and a steep digital low-pass filter ensures that there is a high immunity to vibrations. Coning and sculling compensation is performed at an industry-leading 2 kHz. All internal sensors feature a built-in self test. Xsens Kalman Filter (XKF3i) XKF3i is the proven sensor fusion algorithm that provides the high robustness in orientation of the MTi-20 VRU and MTi-30 AHRS. Divergence monitoring is an important part of XKF3i and ensures that orientation will be correct even under accelerations and magnetic distortions. XKF3i comes with several filter setting profiles that are tuned for specific conditions and environments. Hardware design The MTi 10-series is available in two distinctive form factors. The encased version, with its IP67 rating and 9-pins high-quality push-pull connector offers user-friendly mounting and interfacing. The casing (57x42x23 mm) of anodized aluminum has 7 alignments points in order to ensure accurate mounting. The 9-pins connector features a serial connection, a USB connection and 3 GPIO’s. For customers requiring even more flexibility, a 24-pins OEM board is available that measures only 37x33x12 mm and weighs 11 grams. All products from the 10-series and the high-performance 100-series (including the MTi-G) are fully interchangeable without software or hardware modification. MTi Development Kit For first-time users we offer the MTi Development Kit. This kit includes an MTi measurement unit, a test and calibration certificate, a USB cable, our user friendly MT Software Suite, all in a sturdy suitcase. 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.
