Abstract

In order to achieve low orbit optical compartment for three generations of high-speed laser communication links which between geostationary relay satellite, It had to be designed to meet the use of laser communication terminal background paper for this with the background and the optical compartment specific installation location of the remote machine indicators such as the range of rotation, can pass the time, coarse tracking accuracy, the fundamental frequency, rotational speed, acceleration and weight were analyzed. Obtain azimuth rotation range of ± 135 °, pitching rotation range of ± 60 °, 24h passing time 50525.912s, coarse tracking accuracy 49.4 μrad other indicators, and the typical space laser communication terminal structure were analyzed according to indicators and program aims to analyze the advantages and disadvantages of the requirements proposed structure for this project, tracking frame structure is based on the optical path of the KUDE Cross.
