MAH-A301 MEMS AHRS, six-axis attitude heading reference system, high precision attitude sensor

MAH-A301
MEMS AHRS

Product Overview

The MAH-A301 is a high-reliability and cost-effective 6-axis attitude heading reference system. This module implements full-temperature compensation for bias, scale factor, non-orthogonality error and acceleration-related terms, sustaining stable and high measurement accuracy over long working hours.

It adopts integral vibration damping and hermetic sealing design. It can withstand severe vibration and shock conditions, widely applied in attitude measurement, control and measurement domains including satellite payloads, land vehicles, ships and UAVs.

Core Advantages

Full-temperature calibration compensation from -45℃ to +80℃, compact size, light weight and low power consumption. The built-in adaptive attitude heading algorithm ensures stable roll, pitch and yaw output. It supports 1kHz high-speed sampling and delivers consistent performance under harsh mechanical environments.

Attitude Sensor vs INS Clarification

This MEMS AHRS outputs roll, pitch and yaw attitude data only, without position or velocity navigation solving. If you need a full inertial navigation system (INS) which calculates position and velocity, please check our FOG inertial navigation product.
