Summary:PROBLEM TO BE SOLVED: To make the throughput of an isochronous command such as a teleoperation command by dividing the processing of an isochronous command signal that is received in an equal interval into plural steps, accumulating a competitive internal processing request in a buffer and processing it in a gap between isochronous command processing. SOLUTION: A command preprocessing circuit 1b accumulates an isochronous command signal 4 that is sent from the earth to an artificial satellite through an interrupt signal 22 and detects Tail sequence. A buffer 2 temporarily accumulates an internal processing request 5 such as an HK command and an HK telemetry. A signal processing circuit 3c divides the processing of an isochronous command signal into plural steps and executes each step processing and internal processing with the signal 22. A timer circuit 21 makes time from Tail sequence detection till distribution start of output data to a user's device constant by setting an interrupt interval so that each step processing and competitive internal processing may be finished within the interrupt interval.
