Provided are an apparatus and a method for verifying a reception and execution status of telecommand in a satellite control system. The inventive apparatus for informing a satellite control system of a reception and execution status of telecommand in a satellite comprises a telecommand receiver for receiving a telecommand signal transmitted from a satellite control system, a link control unit for extracting a command transfer frame from the telecommand signal received in the telecommand receiver, judging whether or not the extracted command transfer frame is valid, and providing corresponding link verification telemetry information to a telemetry transmitter, a telemetry information database for storing a set of telecommand execution verification telemetry mnemonics or measured values, a telecommand/telemetry unit, when the telecommand is executed, for acquiring an execution verification telemetry mnemonic responding to the telecommand from the telemetry information database, and the telemetry transmitter for generating a telemetry transfer frame having the link verification telemetry information provided by the link control unit and the telecommand execution verification telemetry mnemonic acquired by the telecommand/telemetry unit as data field, and sending the generated telemetry transfer frame to the satellite control system.
