Product Description

Inertial Navigation System Provides Long-term Stability in Harsh Environmental Conditions

The fiber-optic inertial measurement unit IMU300F-DGI is composed of a three-axis closed-loop fiber-optic gyroscope and an accelerometer with high cost performance, and is realized through a multi-sensor fusion and navigation calculation algorithm to meet the requirements for accurate measurement of information such as attitude, course and position in application fields such as medium and high-precision mobile measurement systems and medium and large unmanned aerial vehicles.
The inertial measurement unit consists of three accelerometers and three optical fiber gyroscopes and is used for measuring the acceleration and the angular velocity of a carrier and sending the information to the information processing circuit; and the information processing circuit performs navigation settlement by using the acceleration and the angular velocity measured by the inertial measurement unit and simultaneously receives satellite navigation information of a satellite receiver as a reference to perform combined navigation, The navigation error of the inertial navigation is corrected, and the navigation information is output through the information interface unit.

Product 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.
