Abstract:
The telecommand execution apparatus and method of a geostationary satellite and the telecommand execution apparatus and method of a satellite control system are provided to verify whether a telecommand such as a time-tage telecommand which is executed at a preset time is accurately performed, automatically, thereby minimizing the intervention of an operator and improving the real-time processing performance. A telecommand receiver(110) receives a telecommand signal from a satellite control system, and then extracts a telecommand transfer frame from the received telecommand signal. A link control unit(130) determines the validity related to whether the extracted telecommand transfer frame is normally transmitted. An on-board computer(150) extracts a telecommand packet from the telecommand transfer frame, and then determines whether the extracted result is a real-time telecommand or a time-tage telecommand which is executed at a preset time. A time tag telecommand memory(170) receives a time tag command from the on-board computer, and then stores the command until the on-board computer executes the command. A telemetry transmitter(190) generates a telemetry transfer frame including general telemetry data and a command execution verification word, and then transmits the generated telemetry transfer frame to the satellite control system.
Abstract:
An apparatus for transceiving remotely-measured data and a method thereof are provided to enable a satellite control system which receives the remotely-measured data from the satellite to easily and conveniently restore the received data. The first grouping part(310) classifies remotely-measured data about the states of plural subsystems comprising a satellite according to each subsystem, and then assigns the first identifier to the first group. The second grouping part(320) classifies the second groups within the first group according to the standards which is set up by a user in advance, and then assigns the second identifier to the second group. A data insertion part(330) inserts the first and second identifiers and the remotely-measured data, which belongs to the second group having the second identifier, into a data field of a transmission frame. A data configuration information insertion part(340) inserts data configuration information about the configuration relation of the data field into a data configuration information field.
