Abstract

This article describes an experimental facility, which simulates the natural operating conditions of radiative coolers used for cooling photo-detectors of electronic optical equipment of spacecraft. The composition and main properties of the facility and the specific features of thermal vacuum tests at cryogenic temperatures are considered. Results of thermal vacuum tests of the radiative cooler for MSY-GS device used onboard a meteorological spacecraft are provided. The results are in good agreement with in-flight data.
