Xsens MTi-3 (9-Axis IMU + AHRS)

Introduction

The MTi-3 manufactured by Xsens is a nine axis inertial measurement unit. It embeds the following sensors :

• 3 axis accelerometers (measure linear acceleration along X,Y and Z);
• 3 axis gyroscopes (measure angular acceleration along X,Y and Z);
• 3 axis magnetometers (measure magnetic field along X, Y and Z).

The most interesting thing about the MTi-3 is the data fusion algorithm. The AHRS algorithm processes data from the nine sensors to output full-featured 3D attitude and heading (pitch, roll and yaw).

Orientation performance

Roll/pitch Static (RMS)	0.75 deg
Roll/pitch Dynamic (RMS)	1.0 deg
Yaw (heading) Static/dynamic (RMS)	2.0 deg
