IASI Sensor module

Block diagram of the IASI instrument

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.
