MTi-2 VRU

The MTi-2 is a self-contained Vertical Reference Unit (VRU). Its sensors provide calibrated inertial data on the 3D rate of turn, 3D acceleration and 3D magnetic field, while an added sensor fusion algorithm computes 3D orientation data on the basis of a gravity-reference frame: drift-free roll, pitch, and accurate, unreferenced yaw.  

The MTi-2 is a self-contained Vertical Reference Unit (VRU) as a 12.1 x 12.1 mm module. The Xsens optimized strapdown algorithm (AttitudeEngineTM) performs high-speed dead-reckoning calculations at 1 kHz allowing accurate capture of high frequency motions. Xsens’ industry-leading sensor fusion algorithm provides high accuracy and sensor auto-calibration in a cost-effective module for a wide range of (embedded) applications. It relieves users from the design, integration and maintenance of gyroscopes, accelerometers and other sensors.

The MTi-2 is supported by the MT Software Suite which includes MT Manager (GUI for Windows/Linux), SDK, example codes and drivers for many platforms including ROS.
