Low zero stability Integrated Navigation System with Fiber Gyro and Mems Acceleroemter
Product Description
The fiber optic integrated navigation system GI300A is based on a cost-effective closed-loop fiber optic gyroscope, accelerometer, and high-end GNSS receiving board. It is implemented through multi-sensor fusion and navigation calculation algorithms, meeting the precise measurement requirements for attitude, heading, and position information in applications such as high-precision mobile measurement systems and large unmanned aerial vehicles.
