Abstract

This paper introduces this topic research background, satellite communications and satellite test rig overview of basic function, design significance, improving trends, main direction, research topic contents, approaches and the technical route and references. Satellite communication is the key technology of aeronautics. In satellite communications can be divided into the sky satellite in between, and satellite communications between the workstations. This topic research ground simulation system test rig, and through the signal to send, transmission and accept test, complete satellite communications commissioning. Meanwhile, the text introduces satellite

communications test-bed design process. First introduced the basic function of satellite communication test, design the meaning of its existence significance as well as satellite communication test-bed, basic principle and structure, satellite communications, the basic parameters test And analyses the stress analysis and more detailed strength check calculation, and the stiffness of trajectory design and its feasibility, main components movement of drawing; The focal point of design is to consider all the components meet function requirement, and can effectively achieve the design purpose, also make the products can meet the design requirement, mechanical parts to reach the design

purpose. In the end the English teacher delivery literature translation.
