Product Description
This inertial navigation system integrates precision laser gyroscopes and quartz accelerometers with a modern strapdown architecture to deliver accurate navigation and attitude information. Supported by real-time navigation algorithms, the system offers flexible operational modes including hybrid inertial-GNSS and standalone inertial navigation. It continuously outputs essential navigation parameters such as heading, roll, pitch, location, and velocity for maritime applications requiring high reliability and accuracy.


Key Advantages

  • High Stability Heading Output based on precision laser gyros
  • Accurate Motion Attitude including roll & pitch measurements
  • Hybrid GNSS + INS Support for reliable positioning under signal loss
  • Fast Initialization & Autonomous Navigation for different maritime scenarios
  • Robust Strapdown Architecture improving performance and system reliability


Application Fields

  • Surface Vessels (OPVs / Patrol Boats / Survey Vessels)
  • High-Speed Craft / Ferries
  • Maritime Navigation & Positioning Systems
  • Marine Survey & Mapping Platforms
  • Autonomous Marine Vehicles (USV / AUV)
