Abstract


Portable satellite communication earth station is a portable ultra- small aperture satellite communication earth station geosynchronous orbit communications satellite link to a satellite communications network to support multimedia communication services for voice, data, audio and video , and WAN access , is a good means of remote data transmission , video broadcasting and remote command and dispatch operations of the scene of the accident . Portable satellite communications earth station tracking principle is the beacon signals issued by the synchronous satellite captured by the satellite signal receiver or forwarding broadband service signals , their frequency down conversion, and then send a beacon signal is proportional to the DC voltage is detected by the signal processing unit to the servo control system the complete antenna for satellite tracking . Portable satellite communication earth station application environment is often quite poor , and therefore , high demands on the reliability of the equipment , at home and abroad on the portable satellite communication earth station research focuses on how to improve tracking technology optimization and system structure design, research studies of the reliability of the equipment is less. The context of the subject portable satellite communication earth station equipment in the actual application , in order to improve the reliability of the equipment for the center , based on years of research portable satellite communication earth station , the reliability of the method of application of electronic equipment , portable satellite communication earth station equipment for system-level reliability analysis and design ; reliability prediction , reliability allocation , fault tree analysis and reliability design main content .
