The MTi-3 is a self-contained Attitude and Heading Reference System (AHRS). In addition to the data collected and computed by the MTi-1 and the MTi-2, it delivers true North-referenced yaw, or heading.
As a member of the MTi 1-series, the MTi-3 stands out for its small form factor (12.1mm x 12.1mm), easy integration, low cost and robustness – as well as its strapdown integration algorithm. Suitable for a wide range of (embedded) applications, the MTi-3 relieves you of the effort of integrating and maintaining gyroscopes, accelerometers and other sensors as well as of having to design an all-in-one AHRS solution.

Our MT Software Suite has everything you need to operate the MTi-3. The suite contains a specially developed, easy-to-use graphical user interface, as well as drivers for various operating systems. It also offers other useful tools and software programs, such as:
- MT Manager (GUI)
- MT SDK, including programming examples for C, C++, C#, MATLAB, Python, ROS and Nucleo boards
- Magnetic Field Mapper (MFM) calibration tool, as GUI and SDK
The suite comes with complete documentation. Of course, you can also always contact our technical support staff.
