Abstract
This paper reports on the command control system, the telemetry analytic system and the space experiment operation in DEBUT (Deployable Boom and Umbrella Test Satellite). The experimental devices are divided largely into a command control device to operate the mission system of the satellite, and a telemetry analytic device to analyze data for a bus condition or a mission condition. The former device consists of a computer and a command generator. Programs for the latter device has enough room for real-time data processing and display. These devices had relatively simple construction, but the reliability was so high that none of them has developed a malfunction. Because the space experiments were completed earlier than the schedule, some more experiment modes were added. No problems were experienced in interface of the ground station facilities with the command control and telemetry analysis systems. An erroneous interpretation has occurred on the satellite in a command signal because of a cyclic fading in an orbit with a low satellite elevation angle, but the malfunction determining program performed a retransmission by which a correct command was executed. 4 refs., 15 figs., 14 tabs.
