The core inertial sensor of the IR3000 laser gyro inertial navigation system is composed of a three-axis 70-type laser gyro combined with a three-axis quartz flexible accelerometer. It mainly includes: secondary power supply, navigation computer, current-frequency conversion circuit, gyro control board, gyroscope, accelerometer, and mechanical structure. Its main functions are: -       It can provide real-time information such as position, heading, horizontal attitude, speed, angular velocity, etc; -       With effective guidance information, initial alignment can be completed while moving; -       It has self-checking and data storage functions; -       The coordinate system can be aligned with other devices through parameter setting.
