MTi-620 VRU

The MTi-620 is the highest standard in Vertical Reference Units (VRU). Its sensors and sensor fusion algorithm measure roll, pitch, and (unreferenced) yaw. As a part of the MTi 600-series, this module is lightweight and robust as well as cost-effective and easy to integrate.

The MTi-620 is a Vertical 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.

The MTi-620 is supported by the MT Software Suite which includes MT Manager (GUI for Windows/Linux), SDK, example codes and drivers for many platforms including ROS.
