IASI Sensor module

The IASI instrument is composed of a sensor module and two deported electronic units.

The IASI Sensor Module configuration includes baffles around a focal plane assembly and secondary radiator to prevent solar illumination and direct views of other instruments or equipment. Its thermal control design is based on super isolation, radiative surfaces and heaters controlled by the instrument itself (IMS) in nominal operational modes. It uses radiators for general heat rejection and passive coolers for maintaining the detector assemblies at operation temperature.
