Paper Abstract

The paper gives an overview of optical communication activities performed by ESA in international and European intersatellite and satellite-to-ground link experiments and describes the evolution of laser communication technology. It introduces the design of a compact and high-speed adaptive optics system specific for laser communication, which - after testing in ESA's optical ground station (OGS) - will be implemented in small ground-based optical receiver stations for Earth observation satellite data. Finally, a novel homodyne BPSK detection scheme is presented, which may become an enabling technology for short distance coherent transmission through atmospheric turbulence.
