MTi-630 AHRS

The MTi-630 is the highest standard in Attitude and Heading Reference Systems (AHRS). Its sensors and sensor fusion algorithm deliver data on drift-free roll, pitch and true North-referenced yaw. As a part of the MTi 600-series, this module is lightweight and robust, as well as cost-effective and easy to integrate. You can seamlessly integrate the MTi-630 in your application in two ways: either with the header facing down, directly mounted on a PCB, or as a standalone, with a flat cable for communication. It is also highly flexible, with native CAN support.

The MTi-630 is an Attitude and Heading Reference System with a small form-factor design for deep integration into your application. Building on the proven MTi 600-series technology it enables a robust and easy to use orientation tracking. It is designed for easy integration and seamless interfacing with other equipment.
