Description

Product Description
The RLG INS (Dubhe-100) uses laser gyros and quartz accelerometers as core inertial sensors to achieve precise motion measurement. With strapdown configuration and real-time calculation software, the system delivers fast data processing and supports both INS-GNSS combined navigation and standalone inertial modes. It outputs heading, roll, pitch, velocity, and position in real time, providing reliable performance for marine navigation platforms that require high stability and accuracy.


Key Advantages

  • Laser Gyro + Quartz Accelerometer Architecture
  • Strapdown INS with Real-Time Processing
  • Supports Hybrid GNSS/INS and Standalone INS
  • Accurate Heading, Attitude, Speed & Position Output
  • Stable Performance for Marine Guidance Platforms


Application

  • Marine Guidance & Navigation Systems
  • Offshore Surveying and Patrol Vessels
  • High-Speed Craft and Autonomous Marine Platforms
  • Special Mission Ships and Research Vessels
