The FT70A is an inertial angular velocity sensor based on the optical Sagnac effect, designed to measure the angular velocity of a carrier along the product's sensitive axis. The angular velocity sensing unit of this product is an optical fiber ring, which uses a digital closed-loop detection circuit to extract the path difference of light propagating clockwise and counterclockwise caused by external physical angular velocity. Simultaneously, the path difference signal is converted into a voltage signal for closed-loop feedback and control, achieving signal modulation and demodulation to achieve high-precision angular velocity signal detection.
The FT70A three-axis integrated fiber optic gyroscope primarily consists of an optical angular velocity sensitive unit and a signal detection unit, capable of providing gyroscope angular increment information and internal temperature information.
It is primarily applicable to medium to high-precision inertial navigation systems, positioning and orientation systems, servo stabilization systems, and other applications.
The three-axis fiber optic gyroscope provides attitude change information during ship navigation, assisting the autopilot system in heading adjustment and stability control. When used in conjunction with an inertial navigation system (INS), gyroscope data can provide reliable positioning and navigation information in the absence of GPS signals or when GPS signals are interfered with, ensuring safe ship navigation.
