This product is equipped with a high-precision closed-loop fiber optic gyroscope with a full temperature of 0.001 °/h and a 10ug high-precision quartz accelerometer. It uses multi-sensor data fusion technology to combine inertial measurement with GNSS, enabling long-term high-precision integrated navigation. The product also has post-processing function, which can be used to improve the heading, attitude, and position accuracy of the product through post-processing software.
