Patent ID: 7756517

Claim:
An apparatus for informing a satellite control system of a reception and execution status of telecommand in a satellite, comprising: a telecommand receiving unit for receiving a telecommand signal transmitted from the satellite control system; a link control unit for extracting a command transfer frame from the telecommand signal received in the telecommand receiving unit, judging whether or not the extracted command transfer frame is valid, and providing corresponding link verification telemetry information to a telemetry transmission unit; a telemetry information storing unit 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 storing unit; and the telemetry transmission unit 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, wherein the extracted command transfer frame is configured to generate the telemetry transfer frame having the link verification telemetry information provided by the link control unit without being processed by an on-board computer, and wherein the telecommand execution verification telemetry mnemonic is configured to generate the execution verification telemetry mnemonic acquired by the telecommand/telemetry unit after being processed by the on-board computer.
