Land RLG INS (Dubhe-L6)
The vehicle-mounted optical gyro positioning and orientation system employs RLG/FOG gyroscopes and quartz accelerometers in a strapdown configuration. Running advanced navigation algorithms, it provides real-time navigation solutions with multiple operational modes including ZUPT, GNSS-aided, and odometer-integrated navigation. Applications include survey vehicles, tanks, self-propelled artillery, armored personnel carriers, unmanned ground vehicles, high-speed rail, and agricultural machinery.
Key features:
1) Static/moving alignment capability;
2) Autonomous navigation with ZUPT and multi-source fusion;
3) Operation capability in high-latitude (±65°), extreme cold and high-altitude environments;
4) High reliability design.
