PURPOSE: A communication broadcast satellite simulation system, and a remote command data and remote measurement data processing method are provided to check performance and matching function of a payload by using a communication satellite simulator. CONSTITUTION: A communication broadcasting satellite model unit(20) receives a remote command related to a satellite bus, drives a corresponding model, and transmits state information of the satellite bus to a bus user interface(21). The bus user interface(21) transmits a remote command for driving a satellite bus model, receives corresponding remote measurement data and displays it, and drives a payload user interface(22). The payload user interface(22) transmits the remote command to the remote command/remote measurement data processor(23), and the remote command/remote measurement data processor(23) encodes and transmits the remote command to a PCTS(Power, Command and Telemetry System) controller(25) through a TCP/IP interface processor(24). The PCTS controller(25) interprets the remote command and transmits a corresponding command to a PIU(Payload Interface Unit)(26). The PIU(26) analyzes the corresponding command, converts it into a signal determined by each command, and transmits it to each part constituting a satellite payload(27) to control the satellite payload(27).

The verification unit compares the result of the non-coherent accumulation with the verification critical value which is defined in advance(S113). The detection unit declares false alarm(S115). The detection unit declares signal presence(S117).
