GVI-2021112906 2. LiAir 250 PRO System Components 2.1 Inertial navigation system The attitude positioning system is formed by GNSS, IMU, and attitude processing software. Its main function is to provide the position and attitude information of the LiDAR system through GNSS and IMU data processing. - Page 12 GVI-2021112906 source and the photoelectric detection sensor as the receiving element. The distance and angle are measured and recorded according to the principle of laser ranging to determine the orientation information of the measured object. The transmitter in the LiDAR emits an ultra-short light pulse hitting the object and diffusely reflected back to the receiver.
