The MTi 1-series of motion trackers incorporate the latest in advanced sensor fusion and miniature MEMS technologies. The Xsens kit ships with a pre-mounted MTi-3-8A7G6 attitude and heading reference system (AHRS) module, which processes motion, magnetic field, roll/pitch, heading, and reference yaw. It includes a 3D accelerometer/gyroscope combo-sensor, a magnetometer, a high-accuracy crystal and a low-power microcontroller. The microcontroller coordinates the synchronisation and timing of the various sensors, applies calibration models and output settings, and runs the XKF3 sensor fusion algorithm to achieve 9D sensor output.
Through a 24-pin header on the development board, the MTi-3-8A7G6 module interfaces with RS232, UART, I ²C, and SPI for connectivity during prototyping. The MT Software Suite includes logging and visualisation options, intuitive configuration windows, and the ability to export data for use in other programs. The SDK also contains source code for communication and libraries for data processing. The module’s onboard processing reduces the load on the application processor to lower the overall power consumption of the end system, while consuming less than 45 mW.
The MTi 1-Series Development Kit provides a development environment for many MEMS applications, including agriculture, robotics, handheld devices, navigation, and industrial projects.
