An industry-leading development platform
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 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.
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.

Free to download MT Software Suite
The MT Software Suite gives you easy access to the MTi-3 and contains a specially developed, easy-to-use graphical user interface, as well as drivers for various operating systems. It also offers many other useful tools, for example source code and documentation.
The suite comes with complete documentation. Of course, you can also always contact our technical support staff if you have questions.
The MT Software Suite includes different software programs, such as:
MT Manager (GUI)
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
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 (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
