Navigation Grade TDFG120T Fiber Optic Gyroscope
1 Introduction
The fiber optic gyroscope (FOG) is an angular velocity sensor operating on the optical Sagnac effect. Equipped with high-performance all-digital closed-loop detection technology, it outputs real-time angular velocity data of the carrier through serial communication. For inertial navigation systems, either three orthogonal single-axis high-precision FOGs or an integrated three-axis FOG configuration serves as the core sensing unit. This configuration enables precise measurement of angular velocity information in three orthogonal directions relative to inertial space.
2 Application
This system is applicable to inertial navigation and attitude reference systems across multiple domains, including guided munitions , aircraft , land vehicles , marine vessels/submersibles , orbital detection platforms , and medium-to-high-end industrial applications .
