Paper Abstract

The Euclid Imaging Channels Instrument of the Euclid mission is designed to study the weak gravitational lensing cosmological probe. The combined Visible and Near Infrared imaging channels will be controlled by a common data handling unit (PDHU), implementing onboard the instrument digital interfaces to the satellite. The PDHU main functionalities include the scientific data acquisition and compression, the instrument commanding and control and the instrument health monitoring. Given the high data rate and the compression needs, an innovative architecture, based on the use of several computing and interface modules, considered as building blocks of a modular design will be presented.
