FG-70/70C/H single-axis fiber optic gyroscope
◾ Product introduction
FG-70/70c /H single-axis fiber gyroscope is an all-solid-state
high-precision digital closed-loop high-precision single-axis fiber
gyroscope integrating optics, machinery and electricity. Based on
SAGNAC principle, it is composed of SLD light source, optical fiber
coupler, photoelectric detector, integrated optical phase
modulator, optical fiber sensing ring, circuit and structures.
Type C is iterated on the basis of FG-70 fiber optic gyroscopev
with high stability, high reliability and higher performance
indicators. H type uses higher grade components, more stringent
production test process to achieve the level of navigation.
It is widely used in navigation guidance and control field.
