Product Description

The Dubhe-M48 Marine Inertial Navigation System (INS) provides high-precision, long-endurance navigation for a wide range of maritime platforms. Featuring laser/FOG gyroscopes and quartz flexure accelerometers as core sensors, the system uses a strapdown with modulation architecture and advanced navigation algorithms to deliver real-time navigation solutions.

The Dubhe-M48 supports multiple operational modes, including pure inertial navigation, GNSS-aided navigation, and velocity-integrated navigation, offering comprehensive full-state navigation parameters to meet the requirements of modern marine vessels.

Applications:

  • Maritime vessels

  • Ship platforms requiring high-precision and long-endurance navigation

Key Features and Capabilities:

  1. Real-time navigation computation for accurate vessel positioning

  2. Pure inertial, GNSS-aided, and velocity-integrated modes

  3. Full-state navigation parameters including heading, roll, pitch, speed, and position

  4. Reliable navigation for diverse marine operations

Keywords: High-precision marine INS, velocity-integrated navigation system, laser gyro INS, maritime RLG INS, strapdown marine navigation, real-time ship navigation, quartz accelerometer INS
