The Telemetry, Command, and Precision Control System for the GRIS-FKI-1 Space Experiment Onboard the International Space Station

Resumo

The telemetry, command, and precision control system of the GRIS (γ- and X-ray radiations of the Sun) instrument for the future GRIS-FKI-1 space experiment is described. This experiment is aimed at investigating nonstationary hard X- and γ-ray fluxes from the Sun onboard the International Space Station. Compared to the resources provided by onboard systems, the set of proposed hardware greatly expands the capabilities of the instrument in the acquisition of service data and control, including the precision control, of the detectors characteristics. The system also helps to improve the thermal conditions and calibrate the spectrometric detectors of the instrument during an experiment.
