HS-70 is an all solid state high-precision digital closed-loop single axis fiber optical gyroscope that integrates optics, mechanics, and electronics. Based on the SAGNAC principle, it consists of an SLD light source, fiber coupler, photodetector, integrated optical phase modulator, fiber sensing ring, circuit, and structural body. It follows the classic design concept of traditional fiber optical gyroscope and adopts mature fiber optic gyroscope manufacturing technology. HS-70 combines the advantages of similar fiber optic gyroscopes at home and abroad, with outstanding advantages such as small size, light weight, low power consumption, fast start-up, simple interface, and easy use. It is an ideal choice for low precision angular rate sensors in the control field and widely used in navigation guidance and control fields.
