Introduction
The 3DM-GX1® is an advanced orientation sensor that integrates three angular rate gyros, three orthogonal DC accelerometers, and three orthogonal magnetometers. It features a multiplexer, a 16-bit A/D converter, and an embedded microcontroller to provide orientation data in dynamic and static environments. It supports full 360-degree angular motion on all axes and outputs data in matrix, quaternion, and Euler formats. The sensor can output temperature-compensated, calibrated data at update rates of 350 Hz and supports RS-485 network protocol for deploying multiple nodes.

Technical Details
The 3DM-GX1® uses triaxial gyros for dynamic orientation tracking and triaxial accelerometers and magnetometers for static orientation. It features a programmable filter algorithm for real-time blending of static and dynamic responses, providing fast response and drift elimination. Full temperature compensation ensures performance across a wide range of temperatures. The sensor's small size makes it ideal for OEM applications.
