| High Light | Fiber Optic Gyroscope INS Unit ，GNSS Aided Inertial Navigation Unit | ||
This product features a high-precision three-axis integrated fiber optic gyroscope, a compact quartz flexible accelerometer, and a mobile survey-grade multi-mode multi-frequency GNSS receiver with autonomous Beidou support. Utilizing advanced intelligent composite navigation algorithms and Kalman filtering, it is optimized for GNSS occlusion and multipath interference scenarios, enabling high-precision measurement of heading, attitude, velocity, and position for mobile platforms.
The INS also has a variety of sensor interfaces, which can meet the requirements of long-term, high-precision and high-reliability navigation in complex environments such as urban canyon, and can be used for navigation and control of various platform systems.
