SILEX: Overview on the European optical communications programme

Research output: Contribution to journalArticlepeer-review

Abstract

SILEX (Semi-Conducteur Intersatellite Link Experiment) is the first civilian optical communications programme (in the frame of ESA DRTM). It will demonstrate in 1997 high data rate transmission between a Low Earth Orbit Satellite (SPOT IV, built by MMS for CNES) and a Geostationnary spacecraft (ARTEMIS, realized by ALENIA for ESA). After the opto/mechanical/thermal qualification obtained mid of 1994, the SILEX programme is entered in an intensive phase with: - the integration/validation for the LEO flight model (PASTEL) - the preparation of integration of the GEO qualification STM and electrical/SW models (OPALE). The article describes the overall development status including the major terminal validation steps as well as the significant technological progress obtained through the qualification at equipment/terminal level.
