Product Description

Compact Inertial Navigation System Provides Efficient Navigation Solutions in Limited Space
 

Product Description

The fiber optic integrated navigation system IMU300F-DGI is composed of three-axis closed-loop fiber optic gyroscope, accelerometer and navigation board with high cost performance, which is realized by multi-sensor fusion and navigation algorithm to meet the requirements of accurate measurement of attitude, heading, position and other information in the application fields of medium and high precision mobile measurement systems, medium and large
 

Features

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, course, 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. 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.
