In order to meet the changing needs of customers in the satellite video communication market,this paper introduces the status quo of satellite vehicle use,analyzes the mission characteristics of satellite communication vehicles,and starts from the Equivalent Isotropically Radiated Power(EIRP),the relationship between rate and bandwidth,builds a digital system.The system can select the most suitable satellite communication vehicle for the target task according to the needs of users,and can automatically configure satellite communication parameters,effectively improve the work efficiency of engineering and technical personnel to perform satellite communication tasks.
