Product Description

Low Zero Stability Integrated Navigation System with Fiber Gyro and Mems Acceleroemter

Product Description

 

The fiber optic integrated navigation system GI300A is based on a cost-effective closed-loop fiber optic gyroscope, accelerometer, and high-end GNSS receiving board. It is implemented through multi-sensor fusion and navigation calculation algorithms, meeting the precise measurement requirements for attitude, heading, and position information in applications such as high-precision mobile measurement systems 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 of the inertial solution are output, in which the pitch and roll are required to be kept accurate, with a certain course keeping function in a short time and meter-level positioning accuracy in a short time.In combination navigation mode, it is possible to output post-processing information for NovAtel's IE post-processing software to process.
• After the pure inertial mode (that is, 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.
