Abstract: A real time synchro division set is provided, that can receive high speed telemetric baseband signals from spacecraft. It is able to divide the download data stream from the spacecraft, being composed of several different signal sources and complies well with the CCSDS standard in packet telemetry, forming them into different kinds of data streams. The demand of time division multiplex transmission of several kinds of data in the same physical channel is achieved. The device is applicable to the advanced space telemetry system.
