A modular design for the ARIEL on-board electronics
Abstract
The ARIEL (Atmospheric Remote-sensing Infrared Exoplanet Large-survey) Mission has been selected by ESA as the fourth medium-class (M4) scientific satellite of the Cosmic Vision Program, to be launched in 2028. ARIEL aims at the study of the atmospheres of a selected sample of warm and hot exoplanets mainly by means of primary and secondary transit spectroscopy. The payload is based on a 1-m class telescope ahead of a suite of instruments: two spectrometric channels covering the band 1.95 to 7.80 µm and four photometric channels working in the range 0.5 to 1.9 µm. AIRS, the ARIEL IR Spectrometer, is the main instrument of the payload, connected to and operated by the Instrument Control Unit (ICU), in charge of the overall Instrument Control, and by the Telescope Control Unit (TCU), whose actual aim is the thermal monitoring of the telescope and the fine thermal regulation of the AIRS detectors Control Thermal System (TCS). Here we mainly describe the baseline ARIEL on-board electronics architecture, from the AIRS output to the electrical I/F to the Service Vehicle Module (SVM).
