Attitude, Heading & Motion Sensing

Attitude, heading, and motion sensing supports precise orientation and movement tracking for marine applications, allowing vessels and subsea platforms to maintain stability and control in changing conditions. These technologies provide dependable measurements of pitch, roll, yaw, and dynamic motion to strengthen navigation accuracy and mission performance across coastal, offshore, and deep water operations.

This category presents key suppliers of inertial sensors, motion reference units, attitude and heading reference systems, and integrated sensing packages that deliver consistent results for ships, remotely operated systems, and autonomous assets in demanding marine environments.
