Product Introduction

FG-98C is a fully solid-state, digital closed-loop, tactical-grade single-axis fiber optic gyroscope. Based on the SAGNAC principle, it consists of an SLD light source, fiber coupler, photodetector, integrated optical phase modulator, fiber sensing coil, circuit, and structure. The C model is an upgraded version of the FG-70, featuring high stability and reliability while delivering enhanced performance indicators. The H model adopts higher-grade components and stricter manufacturing and testing processes, achieving navigation-grade gyroscope performance. They are widely used in the fields of navigation, and control.
