INS800 series fiber optic GNSS/INS integrated inertial navigation system is a high-precision navigation equipment independently developed and produced by our company,which can provide accurate position,speed,and simulation in the depth of 8,000 meters.It has high-precision  fiber optic gyroscope,accelerometer and internal GNSS receiver.It can also receive peripheral auxiliary information,such as DVL,USBLand LBL  information.

Fiber optic gyroscope adopts high-precision three-axis fiber optic gyroscope developed and produced by our company.The fiber optic gyroscope adopts all-digital closed loop and shared doped SLD light source fiber optic gyroscope scheme.The optical path part consists of light source,coupler,integrated Y waveguide,fiber optic sensing ring and detector.Through the breakthrough of erbium-doped fiber source   technology,zero start technology,scale factor error control technology and many other key technologies,so that the fiber optic gyro in the  operating temperature range of-45°C-70℃,zero start conditions,zero bias stability is better than 0.008/h(1o).
