Fiber Optic Integrated Navigation System
Product Features
The fiber optic integrated navigation system S300D is based on cost-effective closed-loop fiber optic gyroscope,accelerometer and high-end GNSS receiving board, through multi-sensor fusion and navigation solution algorithm implementation to meet the needs of medium and high-precision mobile measurement systems, large UAVs, etc.
The application field requires accurate measurement of attitude, heading and position information.
Application scenarios
The system has a combined inertial/satellite navigation mode and a pure inertial mode.
The satellites that can be received by the GNSS receiver in the inertial/satellite integrated navigation mode satellite positioning information for combined navigation; output inertial solution position after losing signal speed attitude, with meter-level positioning accuracy in a short time.
After the pure inertia mode is started, it has the function of accurate attitude measurement and can output pitch rolling and heading, pure inertia can statically seek north.
