MTi 1-series

Tags: IMU | VRU | AHRS | Inertial sensors | Accelerometers | Gyroscopes

The MTi 1-series module is a full-featured, self-contained AHRS, VRU and IMU on a 12.1 x 12.1 mm PCB. The MTi 1-series is an excellent choice for use in high-volume applications that require robustness from the latest miniature MEMS technology.

  • Uniform software/hardware interface over product lifetime
  • Always best-in-class inertial sensors incorporated
  • Industry-leading signal processing pipeline and orientation algorithm


The MTi 1-series module is a full-featured 3D Attitude and Heading Reference System (AHRS), Vertical Reference Unit (VRU) and Inertial Measurement Unit (IMU). The PCB features the proven XKF3TM sensor fusion algorithm on-board and will incorporate the latest inertial MEMS technology, while keeping the software and hardware interface the same. This makes it ideal for users who want to benefit from the advances in MEMS technology, but cannot or do not want to invest in costly development, if a component is no longer available.

The Development Kit with the extensive MT Software Suite allows system integrators and evaluators to start development within minutes.


MT Software Suite

The MT Software Suite gives easy access to Xsens’ products. The suite contains a specially developed and easy-to-use graphical user interface, as well as drivers for various operating systems and many other useful tools, example source code and documentation.

Although it is easy to set up the MTi via the low-level XBus protocol, communication is made easy with the Xsens Device API (XDA) which is completely in C-code.

MT Software Suite Includes:

  • MT Manager
  • MT SDK with the following software development tools
    – XsensDeviceApi.dll (XDA) – DLL C interface
    – XDA source files – C, C++ wrapper
    – Example source code for MATLAB, Python, C++, C#, ROS and Nucleo boards
  • Magnetic Field Mapper executable (GUI) and MFM SDK
  • Complete documentation
