The Research Of Tracking And Pointing Mechanism For One-To-Multiple Laser Communication Terminal

In order to meet the requirements of the laser communication network LCT (Laser Communication Terminal) coarse tracking system. A new structure of eccentric cross universal frame for coarse tracking which is based on rotating parabolic is put forward in this paper. The size and weight of the structure are reduced and the main technical indicators of the system can be achieved experimentally. To achieve the acquisition, pointing, and tracking function of the system with the miniaturized and lightened structure, the servo control unit of the one-to-many communication LCT system is designed.By experiments and analysis, the conclusion is:The volume and weight of the LCT coarse tracking system reached the requirements of light weight and compactification.
