Description

Product Description
The Dubhe-48 Ring Laser Gyro Inertial Navigation System incorporates laser gyroscopes and quartz accelerometers as its core inertial sensors. Built on a robust strapdown INS architecture, the system executes real-time navigation computation and supports multiple operational modes, such as GNSS-aided INS and pure inertial navigation.

Designed for maritime platforms that require good-quality guidance and long-term reliability, the Dubhe-48 outputs highly accurate heading, attitude, speed, and position data, enabling consistent guidance performance under complex marine dynamics. As a compact maritime guidance INS guidance system, it is suitable for both unmanned and manned vessel navigation scenarios.


Key Advantages

  • High-precision RLG + quartz accelerometer inertial sensing
  • Real-time strapdown navigation computation
  • Supports INS-only & INS-GNSS combined navigation modes
  • Provides accurate heading, roll, pitch, speed & position outputs
  • Stable performance under vibration and environmental variation
  • Suitable for integrated navigation system deployments on marine platforms
  • Supported by professional guidance INS system provider / manufacturer


Application Fields

  • Marine INS navigation system deployment
  • Surface ships & naval vessels
  • USV / UUV platforms
  • GNSS-aided maritime guidance
  • Autonomous vessel navigation & control
  • Mission-critical maritime positioning
