This NS-N2B Static Fiber Optic Gyro North Finder adopt closed-loop fiber optic gyroscope or high precision MEMS gyroscope as the core components. It is mainly composed of inertial measurement unit, digital signal processing unit and the organizations of the mechanical parts, and it has a GPS/GNSS/BD receiver and odometer sensor components such as expansion of position. It can provide the carrier with true north azimuth Angle. At the same time, as well as the carrier of motion, speed and position information. Products are mainly used in coal mining, oil drilling, tunnel construction and geodesy, it can also be used for static positioning and orientation of the ground object.
