Visit Website Contact

The miniAHRS is a lightweight and compact attitude and heading solution that combines three axes of precision accelerometers, gyroscopes and fluxgate magnetometers with state-of-the-art sensor fusion to deliver robust high-accuracy heading, pitch and roll data for both static and dynamic applications.

The system features specialized algorithms tailored to the differing motions of land, air and marine vehicle platforms, as well as gimbals and antennas. All sensing elements are fully calibrated over the entire operational temperature range for superior performance.
