﹒Product Introduction﹒
This product integrates a high-precision fiber optic gyroscope, a high-precision quartz flexural accelerometer, and a mobile mapping-grade multi-mode, multi-frequency GNSS receiver supporting autonomous BeiDou functionality. Through advanced intelligent integrated navigation algorithms and Kalman filtering, and optimized for GNSS obstruction and multipath interference, it enables high-precision measurement of heading, attitude, velocity, and position of moving vehicles.
This inertial navigation system also features multiple sensor interfaces, including GNSS, odometer, DVL, and barometric altimeter, effectively meeting the demands of long-duration, high-precision, and high-reliability navigation applications in complex environments such as urban canyons. It can be used for navigation and control of various unmanned systems.
