SEDHI: development status of the Pléiades detection electronics
Author(s): Didier Dantes; Jean-Marc Biffi; Claude Neveu; Christophe Renard

Paper Abstract

In the framework of the Pléiades program, Alcatel Space is developping with CNES a new concept of Highly Integrated Detection Electronic Subsystem (SEDHI) which lead to very high gains in term of camera mass, volume and power consumption. This paper presents the design of this new concept and summarizes its main performances.

The electrical, mechanical and thermal aspects of the SEDHI concept are described, including the basic technologies: panchromatic detector, multispectral detector, butting technology, ASIC for phase shift of detector clocks, ASIC for video processing, ASIC for phase trimming, hybrids, video modules... This concept and these technologies can be adapted to a large scale of missions and instruments. Design, performance and budgets of the subsystem are given for the Pléiades mission for which the SEDHI concept has been selected. The detailed performances of each critical component are provided, focusing on the most critical performances which have been obtained at this level of the Pléiades development.
