3DM-GX5-AHRS
Overview
The 3DM-GX5-AHRS is a high-performance Attitude and Heading Reference System (AHRS) that integrates triaxial accelerometers, gyroscopes, and magnetometers with a pressure altimeter. It features dual on-board processors running an Auto-Adaptive Extended Kalman Filter (EKF) to provide precise dynamic attitude estimates. The module is housed in a compact aluminum enclosure and supports both USB 2.0 and RS232 interfaces for flexible system integration.
Why Choose This Part
The dual-processor architecture offloads complex EKF calculations from the host controller, ensuring high-rate data output even in demanding dynamic conditions. It offers a wide input voltage range of 4V to 36V and is fully temperature compensated from -40C to +85C. The inclusion of a pressure altimeter and magnetometer allows for full 3D orientation tracking with vertical reference stability.
Applications
Getting Started
Connect the module to a PC via the micro-USB port and use the MicroStrain MIP Monitor software for initial configuration and real-time data visualization. Developers can integrate the sensor into custom C++, Python, or ROS environments using the open-source MicroStrain Communication Protocol (MIP) SDK.
