Gyrocompass ER-FNS-02

Introduction
 
The FOG north seeker is mainly used for quickly and autonomously determining the true north direction. The Earths rotational speed is obtained through high-precision fiber optic gyroscope. The signal of the Earths rotational speed is calculated to determine the Angle between the gyroscopes main axis and the Earths true north direction, providing azimuth information for the carrier. It does not rely on satellite signals and can provide accurate true north direction references in closed or complex environments.
 
The ER-FNS-02 series single-axis FOG north seeker is mainly composed of a high-precision single-axis fiber optic gyroscope, a high-precision rotation mechanism, a digital signal processing unit, and other mechanical components.
 
 
Applications
 
High-precision geodetic surveying: Topographic mapping in remote areas (mountainous regions, deserts), terrain surveying in areas without satellite signals, orientation calibration of geodetic control points, replacing traditional optical theodolites;


Precision equipment calibration: Installation and calibration of radar antennas and satellite receiving antennas, ensuring that the reference axis of the equipment is aligned with the true north direction;


Precise measurement experiment: Directional reference for quantum physics and astrophysics experiments, ensuring the stability of the experimental setup and the accuracy of the data;


Tunnel Engineering: Precise orientation of tunnel boring machines (TBM), especially for long-distance tunnels (such as high-speed rail tunnels and urban subways), controlling the excavation direction in the underground enclosed environment to avoid deviations.
