Abstract :
Virtual radio space control system is the necessary tendency to spacecraft control. Spacecraft control system based on Virtual radio is different from traditional software radio in the data paralleled transmission and time synchronization. Dynamic time-division multiplexing transmission mode is presented by analyzing the data paralleled and synchronous transmission. The problem caused by traditional software radio frame that paralleled high speed data being blocked by low speed data is solved in the transmission time delay. According to uncertainty problems of data transmission and dealing time delay caused by the asynchronous work model of the virtual radio spacecraft control system, the method of time synchronization based on the data frame structure is presented, and the measure synchronization is preformed in a general way.
