    Leading subsea Inertial Navigation Systems (INS) and Motion Reference Units (MRU) manufacturers
    provide ruggedized navigation and motion sensing for ROVs, AUVs, and hydrographic surveys. Key industry players include Exail, Inertial Labs, Teledyne Marine, SBG Systems, Advanced Navigation, Micro-Magic Inc, and Norwegian Subsea. 
    Key Subsea INS/MRU Manufacturers & Technologies: 
    • Exail: Manufactures Octans, Rovins, and Phins inertial navigation systems, providing high-accuracy FOG-based systems for subsea positioning and mapping.
    • Inertial Labs: Produces MRU-ES (Enhanced Subsea) and other MEMS-based MRUs tailored for UUV/AUV/ROV tracking.
    • Teledyne Marine: Known for dynamic motion sensors and gyros for vessel motion compensation and subsea pipeline survey.
    • Micro-Magic Inc: Offers ruggedized subsea MRUs designed to provide robust roll/pitch/heading and heave data for underwater environments.
    • Norwegian Subsea: Specializes in robust, high-accuracy Motion Reference Units (MRUs) for offshore, subsea, and marine energy sectors.
    • SBG Systems: Offers the Ekinox and Navsight series, commonly used for subsea navigation and surveys.
    • Advanced Navigation: Produces Fiber Optic Gyro (FOG) INS for underwater navigation. 
    These systems are essential for providing real-time data regarding heave, sway, surge, pitch, roll, and heading, designed to handle deep water pressure and high-vibration scenarios.
