The Dubhe-12 Ring Laser Gyro Inertial Navigation System utilizes high-performance laser gyroscopes and quartz accelerometers as its core sensing elements. Built on a mature strapdown inertial navigation architecture, it integrates real-time navigation algorithms to compute and output navigation parameters with high precision.
The system supports multiple operational modes, including standalone inertial navigation and INS/GNSS hybrid navigation, enabling flexible deployment across various maritime platforms. It delivers accurate heading, roll, pitch, speed, and position information, meeting the requirements of modern naval INS navigation system applications that demand good-quality guidance and robust performance under dynamic conditions.
As a professional guidance INS system provider and manufacturer, the Dubhe series is designed for long-term mission performance in harsh marine environments.
