Acquisition, Scanning and Control Technology for Inter-satellite Laser Communication

2021 IEEE 16th Conference on Industrial Electronics and Applications (ICIEA), 2021
Due to the complex space environment, it is very difficult to establish communication links between satellites efficiently and quickly. Considering laser power limitation and environmental conditions, the gazing/scanning method is selected to achieve inter-satellite laser communication. Firstly, this paper establishes the theoretical model of the field
