The Application Software of the Ariel Instrument Control Unit

The ARIEL mission has the task of conducting a large, unbiased spectroscopic survey of exoplanets, in order to explore the nature of exoplanet atmospheres and interiors and, through this, the key factors affecting the formation and evolution of planetary systems in our galaxy.Ariel is composed of two scientific instrument: one is the FGS which provides the Fine Guidance System capabilities and in addition combines a VIS photometer and a NIR spectrometer.The other instrument is the Ariel IR Spectrometer (AIRS) which provides spectra with resolution between 30 and 100 on a spectral band between 1.95 and 7.8 micrometers.This paper will focus on the control SW of the AIRS instrument, which is executed on the Instrument Control Unit (ICU) Hardware.
