Design And Research Of Key Technology In The OTM GEO-satellite Communication System

SCOTM (Satellite communication On-The-Move) system is a special application in the terrestrial satellite communication system. It is a nice broad practical application of modern communication system. But its exorbitant cost of manufacture is a mainly factor that decrease it become popular.In this paper, author emphasize on the studying and designing of the entire SC-OTM system. Analyze the key technology in the system designing, such as communication mode, antenna prototype, steady console tracking mode, tracking receiver signal generating, etc. Present a type of Ku-band SC-OTM system, which has many good virtues, such as all-purpose applications, high performance ratio it cost, low profile, etc. Also present other relevant devices or facilities designing method and selecting. The communication system is working on the DSSS mode, which has intrinsic ability of information secreting when transmitting. The system has been validated by practical using, and performed good characteristics. It will be popular using in many fields, such as military communication system, emergency communication system, incidental affair communication system, etc.
