An industry-leading development platform

Active heading stabilization

AHRS


The MTi-3 inertial measurement unit is a self-contained attitude and heading reference system (AHRS) that delivers true-north-referenced yaw, or heading.

smallest-grade-form-factor

Smallest industrial grade form factor

As part of the MTi 1-series, it is among the smallest of its kind available, with each module measuring only 12.1 × 12.1 mm and weighing <1 g.

All in one solution

Comprehensive, all-in-one solution

Suitable for a wide range of (embedded) applications, the MTi-3 is part of the MTi-1 series. It's a comprehensive, all-in-one solution that eliminates the need for you to design your own system and incorporate separate gyroscopes, accelerometers and other sensors.

This provides you with easy access to all the functions of your MTi from the comfort of your office. MT Manager enables recording and playback of data, real-time data viewing, including graphs, and easy configuration of settings.

MT SDK

MT SDK

This program is for self-developing your software to communicate with our sensor, including programming examples for C, C++, C#, MATLAB, Python, ROS, and Nucleo/STM boards.

Magnetic Field Mapper

Magnetic Field Mapper

Magnetic Field Mapper (MFM) is a calibration tool for conducting magnetic calibration, available as GUI for Windows and as SDK.

Xsens MTi-3 providesprecise attitude report forblueprint subsea beacons

The Xsens MTi-3 module is used within the SeaTrac beacons to provide highly accurate and stable attitude reference. The Xsens module not only measures magnetic heading but combines both pitch and roll angles to provide the user with a very precise attitude report of their subsea asset.
