DEVICE AND METHOD FOR OPTICAL COMMUNICATIONS BETWEEN A SMALL AUTONOMOUS TERRESTRIAL TERMINAL AND A SATELLITE

摘要

The invention relates to a communication system by optical link between a terminal disposed at a fixed point relative to the terrestrial surface, said "ground terminal" having a directional optical transmitter, and a remote relay, mobile relative to the ground terminal, the ground terminal comprising means for automatically orienting the directional optical transmitter in elevation and azimuth towards the remote relay, with a precision compatible with the establishment of an optical communication between the fixed terminal and the remote relay. Preferably, the ground terminal also comprises autonomous power supply means.
