The ISM3D Attitude & Heading Reference System is an advanced MEMS-based AHRS for underwater naval vehicles & platforms. The ISM3D is an advanced MEMS-based AHRS that provides high-accuracy real-time roll, pitch and heading information for stabilization and control of naval equipment and manned/unmanned underwater vehicles, as well as for navigation aiding in underwater GNSS-denied environments. It provides heading data with accuracy to ±1° of local magnetic north, and pitch and roll data to ±0.07° accuracy. In
environments with large amounts of ferrous metals or other magnetic disturbances, the magnetometers can be deactivated, and heading accuracy can be boosted thanks to a built-in soft and hard iron calibration feature. The unit's low-drift gyroscopes ensure a level of navigation accuracy that could previously only be achieved by fiber optic or ring laser diode based sensors. The underwater AHRS can be provided in an acetal housing depth-rated to 1000 meters, a rugged 6000 meter-rated titanium housing, or as an OEM system.
