High-Performance Inertial Navigation System for Precise Attitude Measurement
Product Description
The GI600A-B0 integrated navigation system is a compact dual-axis rotating MEMS integrated navigation system. Through the realization of multi-sensor fusion and navigation calculation algorithm, it meets the requirements of precise measurement of attitude, heading, position and other information in the application fields of medium and high-precision mobile measurement systems, large unmanned aerial vehicles and so on.
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 GNSS receiver can be used for integrated navigation, and the pitch, roll, course, 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 course 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.
