Xsens MTi 1-Series

The MTi 1-series module is a full-featured 3D Attitude and Heading Reference System (AHRS), Vertical Reference Unit (VRU) and Inertial Measurement Unit (IMU). The PCB features the proven XKF3TM sensor fusion algorithm onboard and will incorporate the latest inertial MEMS technology while keeping the software and hardware interface the same. This makes it ideal for users who want to benefit from the advances in MEMS technology, but cannot or do not want to invest in costly development, if a component is no longer available.

3D orientation and performance specifications

Roll/pitch Static 0.75 deg
Dynamic 1.0 deg
Yaw (heading) Static/dynamic, Magnetic field referenced 2.0 deg MTi-3 AHRS only in a homogenous magnetic field and a filter profile using a magnetic field as a reference.
VRU_general filter profile (unreferenced yaw) < 1 deg after 60 min Active Heading Stabilization (AHS) feature. See section 7.2 for more information.
Output data rate 0 – 100 Hz Accuracy and latency are independent of the output data rate. The output data rate may be an integer divider of 100 Hz or may be triggered by an external pulse (SYNC_IN)
