Electronically steered inter-satellite optical communication system and methods

摘要

Aspects are generally directed to an inter-satellite communication system and method of communicating between satellites. In one example, an inter-satellite communication system includes a first satellite transceiver having an entrance aperture, and a non-mechanical beamsteering device configured to steer a first beam of encoded optical data over a field of view thereof. The first satellite transceiver may include coarse steering optics configured to extend a field of regard of the non-mechanical beamsteering device. During a transmit mode, the coarse steering optics are positioned to transmit the first beam of encoded optical data through the entrance aperture in a direction of a second satellite transceiver. The first satellite transceiver may also include a beam splitter positioned, during a receive mode, to receive a second beam of encoded optical data from the second satellite transceiver and direct the second beam of encoded optical data to an optical sensor.
