Impact Subsea are proud to present the ground breaking ISM3D family of Underwater Attitude and Heading Reference System (AHRS) Sensors. 

Highly Robust, compact and lightweight, the ISM3D is ideal for ROV, AUV and other underwater Heading, Pitch and Roll applications.

With a selectable Inertial Mode, the ISM3D Heading is highly resilient against temporary magnetic interference. 

The ISM3D utilises MEMS based Accelerometers, Angular Rate Gyroscopes and Magnetometers. 

The outputs from each sensor are processed by an advanced fusion algorithm to provide highly stable and accurate Heading, Pitch and Roll.
