Abstract:
Traditional satellite-to-earth data transmission systems are constrained by inefficient relay schemes and/or short-duration data transfers at low data rates. Communication systems described herein achieve extremely high burst rate (e.g., 10 Gbps or greater) direct-to-Earth (DTE) data transmission over a free-space optical link between a spacecraft and a remote terminal, which may be a ground terminal or another space terminal. The optical link is established, for example, when the remote terminal is at an elevation of 20° with respect to a horizon of the remote terminal. In some embodiments, a data transmission burst contains at least 1 Terabyte of information and has a duration of 6 minutes or less. The communication system can include forward error correction by detecting a degradation of a received free-space optical signal and re-transmitting at least a portion of the free-space optical signal.

Claim (Index 10):
A system for free-space optical communications, the system comprising:\n an optical transmitter, on a spacecraft, to transmit a free-space optical signal; and a remote terminal, in optical communication with the optical transmitter, to receive the free-space optical signal, to detect a correctable error in a first frame of the free-space optical signal, to correct the correctable error in the first frame, to detect an uncorrectable error in a second frame of the free-space optical signal received by the receiver, and to request repeat transmission of the second frame of the free-space optical signal in response to detection of the uncorrectable error.
