Radio And Television Satellite Earth Station System Design

In this paper, we put forward a design scheme for the signal transmission system, auxiliary system and surveillance system in satellite television station of jiangsu province. Several pivotal technical problems in designing and actualizing the scheme are also introduced. The scheme has biggish innovations on power amplification, automatism rearrange, perturb resisting, signal attenuation preventing, real time video frequency signal surveillance etc. It has been applied for half a year, which makes it clear that the scheme has full functions and advanced technique, and also is credible.In chapter 1, the principles of satellite transmission are briefly described. Also the conditions needed in salellite transmission route are introduced. We compare and analyze some satellite transmission methods. In chapter 2, we i lluminate the design scheme for satellite earth slat ion. Also we analyze and research the coding way, electromagnetism condition and transmission route. A local color scheme for the signal transmission system is given. Two auxiliary systems called automatism rearrange and power self-regulat ion are designed in chapter3, which makes the rearrange time Jess than 1ms. Then the satellite station can work safely and consecutively. Real time remote surveillance system presented in chapter 4, which has the function of scouting the state of equipment, emergency parameter and video frequency, can reduce the labor intensify of the workers and improve running-efficiency. Lastly, we sum up the research progeny, and indicate several problems needed to be solved.
