The AHRS-II-P is a tactical-grade Attitude and Heading Reference System that utilizes precision 3-axis accelerometers and gyroscopes as well as an embedded fluxgate compass to provide heading, pitch and roll data, as well as high-frequency real-time device rotation data and ongoing gyroscope corrections.

The IP67-sealed device outputs high-accuracy data in both motionless and dynamic applications, and features advanced sensor fusion and specialist algorithms tailored to the specific dynamic motions of manned and unmanned aircraft, naval vessels, land vehicles, gimbals and antennas. All sensing elements are fully calibrated across the complete operating temperature range.
