【Abstract】 By the analysis for the work principle of the unified S-band communication channel(USB) of the telemetry,tracking and command system(TT&C),the simulation structure of the USB TT&C system is designed and also the realization of the simulation for the receiving and transmitting of the USB TT&C system is focused on.The analysis of a few key problems of imitating actual signal,sample rate,combination interference,phase lock loop and filter etc are carried out.The simulation design proposed in this paper provides the technical base for simulation of the satellite TT&C system.更多还原
