Abstract: A free space line of site communication system for communicating between a first destination and a second destination includes a constellation of airborne platforms in a train-like formation, each travelling at a constant speed and distance relative to each other. Each of the airborne platforms includes: one or more inter-airborne platform optical or RF transceivers for communication with a previous and a next neighboring airborne platforms, wherein each inter-airborne platform transceiver is capable of adjusting its velocity to keep a constant speed and distance relative to its neighboring airborne platforms, and one or more up/down link transceivers for communication with multiple ground sites, each ground site having two or more ground optical or RF transceivers. A first airborne platforms closest to the first destination communicates with the first destination and a second airborne platforms closest to the second destination communicates with the second destination.

Abstract: A free space optical communication system (100) and method including a constellation of several satellites (102). Each of satellites including: several inter-satellite optical telescopes (204) for optical communication with multiple neighboring satellites, each inter-satellite optical telescope is capable of adjusting its elevation angle to accommodate changes in the number of satellites in the constellation; and several up/down link optical telescopes (206) for optical communication with multiple ground sites, where each ground site has several ground optical telescopes. As the constellation passes a given ground site, some of the up/down-link telescopes of a given satellite are configured to track at least two respective ground optical telescopes of the given ground site and send data to the ground optical telescope with the clearest line of sight to the given satellite. Moreover, each of the satellites includes optical circuitry (208, 210, 212, 216) for optically processing and switching incoming and outgoing optical signals without converting the optical signals into electrical signals.
