Design And Implementation Of Business Exercise System For Satellite Earth Station

The satellite earth station is responsible for signals transmitting and processing in the satellite communication radio and television technology link.Frontline operators' emergency response capability is directly determines the success or failure of the satellite earth station,therefore,their professional training is essential.The business exercise system has the uplink and downlink of satellite communication,with the same operation facilities as the satellite earth station.It realizes the high power signal receiving and forwarding by using analog transponder,to simulate the working system of the satellite earth station and several interferences,which provides frontline operators a learning and practice platform to improve their emergency response capability.Firstly,the paper puts forward the design concept of the business exercise system,analyzes its structure and working principle,and introduces the function of each module in detail,based on the working system of the satellite earth station.In addition,according to the system working link diagram,the paper establishes the simulated subsystems of primary broadcast station,standby broadcast station,network control,monitor,and simulation practice,tests such subsystems,and verifies their workability.Finally,the paper introduces the application effects of the business exercise system in actual working condition of the earth station,studies the types of faults the system can simulate and the corresponding methods to achieve them,and analyzes how to realize the interference'simulation.
