Industrial grade MEMS 3D motion trackers maintain accuracy under vibrations

August 02, 2012 // By Julien Happich
Xsens has launched its 4th generation of high-performance MEMS based motion trackers (IMU, VRU, AHRS and GPS/INS) to match the requirements in terms of accuracy and robustness for many applications previously depending on fiber-optic gyroscope (FOG) based solutions.

The new MTi product portfolio for industrial applications such as antenna/camera stabilization and unmanned system control offers 7 distinctive models offering 3D orientation, 3D position, 3D velocity, 3D dynamic data and a range of interface options.

The MTi product portfolio consists of two product lines. The MTi 10-series extends the proven technology of the previous generations of the MTi, of which more than 20.000 units have been deployed since 2005. The MTi 10-series improves orientation accuracy while under vibrations with at least a factor of 50. The bandwidth of the accelerometers and gyroscopes has been increased by a factor of 15. Available products are the MTi-10 IMU (Inertial Measurement Unit), the MTi-20 VRU (Vertical Reference Unit) and the MTi-30 AHRS (Attitude and Heading Reference System).

The MTi 100-series is Xsens' new high-performance product line, incorporating state-of-the-art vibration rejecting gyroscopes and a powerful multi-core processing unit running a new embedded sensor fusion core that goes beyond standard Kalman-filter based solutions. Available as MTi-100 IMU, MTi-200 VRU and MTi-300 AHRS, it is an excellent drop-in alternative to the MTi 10-series when extra accuracy is required. The MTi-G-700 GPS/INS is the successor of the MTi-G introduced in 2007. The MTi-100 series can serve as a cost-effective replacement unit for high-grade IMU’s, making the end-product more economically viable.
