| High Light | Fiber Optic INS high-precision navigation ，Marine UAV vehicle navigation system ，Fiber Optic Inertial Navigation System | ||
This inertial navigation system integrates a three-axis high-precision integrated fiber optic gyroscope, a high-precision quartz flexure accelerometer, and a survey-grade multi-mode and multi-frequency GNSS receiver with autonomous Beidou navigation capability. Powered by advanced intelligent integrated navigation algorithms and optimized Kalman filtering, the system is fully optimized to mitigate GNSS signal occlusion and multipath interference, enabling high-precision measurement of heading, attitude, velocity and position for moving carriers.
Equipped with rich expandable interfaces for GNSS, odometer, DVL and barometric altimeter, the system supports long-duration, high-precision and high-reliability navigation in complex scenarios including urban canyons. It is widely deployed for navigation and motion control of various unmanned systems.
