Dubhe-L6 Integrated GNSS-Aided Automotive Inertial Navigation System | Gyroscope Guidance Land RLG INS
The Dubhe-L6 Land RLG Inertial Navigation System (INS) is a vehicle-mounted optical gyro positioning and orientation system designed for high-precision automotive navigation. Using RLG/FOG gyroscopes and quartz accelerometers in a strapdown configuration, the system executes advanced navigation algorithms to provide real-time navigation solutions.
The Dubhe-L6 supports multiple operational modes, including ZUPT (Zero Velocity Update), GNSS-aided navigation, and odometer-integrated navigation, offering accurate and reliable positioning for a wide range of ground vehicles.
Applications:
-
Survey and mapping vehicles
-
Tanks and armored personnel carriers
-
Self-propelled artillery and unmanned ground vehicles
-
High-speed rail and agricultural machinery
Key Features and Capabilities:
-
Static and moving alignment capability for fast initialization
-
Autonomous navigation with ZUPT and multi-source sensor fusion
-
Operation in high-latitude (±65°), extreme cold, and high-altitude environments
-
High-reliability design for continuous and accurate navigation
