Product Description

High Accuracy Inertial Navigation System Three-Axis MEMS Gyro GI300F-A0-DGI

Product Description

The fiber-optic integrated navigation system GI300F-A0-DGI is composed of three-axis closed-loop fiber-optic gyroscope, accelerometer and navigation board based on high cost performance, and is realized through multi-sensor fusion and navigation calculation algorithm to meet the requirements for accurate measurement of attitude, heading, position and other information in application fields such as medium and high precision mobile measurement systems and medium and large unmanned aerial vehicles

Main Functions

• The system has inertial/satellite integrated navigation mode and pure inertial mode.
   
• In the inertial/satellite integrated navigation mode, the satellite positioning information received by the internal GNSS receiver can be used for integrated navigation, and the pitch, roll, heading, position, speed, time and other information of the carrier can be output; After the signal is lost, the position, velocity and attitude calculated by inertia are output, in which the pitch and roll are required to be accurate, the heading keeping function is available in a short time, and the meter-level positioning accuracy is available in a short time.
   
• After the pure inertial mode (i.e., GPS fusion has never been performed after power-on, and if it loses lock again after fusion, it belongs to the integrated navigation mode) is started, it has accurate attitude measurement function, can output the pitch and roll heading, and the pure inertial mode can find the north statically.
