Paper Abstract

We present a new concept to link two ground-based optical stations through a satellite. In our approach the optical relay in orbit is a completely passive one, with no requirements in terms of active control attitude and with a more simple opto-mechanical design. The relay acts as a reference source for the ground stations, equipped with an adaptive optics system to enlarge the photon return and the bandwidth of the transmitted signal. The technological requirements are mainly on the ground side, then technological up-grades are easily obtainable and less cost- demanding.
