Optimized design

The instrument is divided in two "modules":

• an "electronics" module dedicated to the main part of the electronics boxes (processing, management, etc.)

• an 'optics" module dedicated to the optical and opto-mechanical elements, as well as the close proximity electronics: telescopes, interferometer, cold box, proximity detection electronics, metrologies, active cooling, etc. These elements are supported by a stable structure comprising a main plateau and a mezzanine. The compactness obtained enables free space margins to be achieved on the satellite.
