Navigation Grade TDFG120S Fiber Optic Gyroscope
1 Introduction
Fiber optic gyroscope is a kind of angular velocity sensor based on optical Sagnac effect, internal high-performance all-digital closed-loop detection technology, real-time carrier angular velocity information can be output through the serial port. Three single-axis high-precision fiber-optic gyroscopes or three-axis integrated fiber-optic gyroscopes can be used as the core sensors of inertial navigation solution, sensitive carrier relative to the inertial space in three orthogonal directions of the angular velocity information.
2 Application
It is suitable for inertial navigation equipment and attitude reference equipment in the fields of guided weapons, aircraft, vehicles, ships, submersibles, orbit detection and medium and high-end industry.
3 Characteristics
High precision, better stability, flexible design;
All-solid-state design with no moving parts;
Extremely short start-up times and digital outputs for easy integration into digital circuits.
Low noise, low power consumption, low cost;
High reliability and long life
