Description
The Atmospheric Remote-sensing and Infrared Exoplanet Large-survey (ARIEL) is a space observatory and the fourth medium-class (4M) mission of the European Space Agency's (ESA) Cosmic Vision programme. One of the instruments on board ARIEL is Fine Guidance System (FGS). This optic sensor provides high-precision pointing information for the telescope which is an input to its attitude control system. Spacive Sp. z o.o. is responsible for the design of the thermal test setup in the thermal vacuum chamber for the the Space Research Centre of the Polish Academy of Sciences (CBK PAN), which is responsible for the development of the FGS instrument.
In this paper we are presenting design of the test setup in the Thermal Vacuum Chamber, which requires maintaining different interfaces with stable temperature of 30K and 90K for the FGS instrument and supporting electronics. Moreover, we presents the results of thermal analyses, validation test campaign of completed setup and model correlation
