◾ Product introduction
STG-70A three-axis fiber optic gyroscope is a full solid-state
high-precision digital closed-loop fiber optic gyroscope
integrating optics, mechanics and electricity. Based on the
principle of Sagnac, it is composed of SLD light source, fiber
coupler, photodetector, integrated optical phase modulator, fiber
sensing ring, circuit and structure.
Designed for tactical inertial measurement system, it has the
characteristics of high reliability and flexible structure. It is a
highly customized product produced according to the customer's
platform.
