This inertial navigation system is embedded with a three-axis integrated high-precision fiber optic gyroscope, a high-precision quartz flexure accelerometer, and a mobile mapping-grade multi-mode and multi-frequency GNSS receiver that supports independent Beidou navigation functions. Adopting advanced intelligent integrated navigation algorithms and optimized Kalman filtering technology, the system is specially designed to resist GNSS signal occlusion and multipath interference. It enables high-precision measurement of heading, attitude, velocity and position for moving carriers.
Supporting multiple sensor interfaces including GNSS, odometer, DVL and barometric altimeter, the system fully meets the requirements of long-duration, high-precision and high-reliability navigation in complex scenarios such as urban canyons. It is widely applicable to the navigation and motion control of various unmanned systems.
