Paper Abstract

The SILEX system involves a large set of advanced techniques and technologies which need to be merged and confronted. A macroscopic approach makes it possible to consider an optical terminal, with reference to common space fields of activities as a combination of a communication payload, an attitude and orbit control system, an optical instrument, and an on-board data handling system. It requires great technical expertise in areas commonly mastered in these techniques, namely, highly sensitive detectors such as coupled charge detector matrices, avalanche photodiodes, accurate and/or high bandwidth pointing and steering mechanisms, high optical quality mirrors and optical coatings, and accurate thermal control. Basic system and engineering tasks are to be mastered to combine them in an optimal way. This calls, among other things, for requirements analysis to derive the main design drivers and specific constraints with respect to each technique involved, and sizing and configuration of the system.
