Laser Communications Airborne Testbed: Potential For An Air-To-Satellite Laser Communications Link
SPIE Proceedings, 1988The Laser Communications Airborne Testbed (LCAT) offers an excellent opportunity for testing of an air-to-satellite laser communications link with the NASA Advanced Communications Technology Satellite (ACTS). The direct detection laser portion of the ACTS is suitable for examining the feasibility of an airborne terminal.

Secret key agreement for satellite laser communications
2021Free-space optical (FSO) communications offer high-capacity wireless transmission due to their plentiful properties originated from higher carrier frequency. These properties also yield a greater security advantage: the high directionality of the laser beam and the line-of-sight configuration can reasonably restrict an attack model launched by an ...

Diversity Effects in Satellite-Ground Laser Communications Using Satellite Images
29th AIAA International Communications Satellite Systems Conference (ICSSC-2011), 2011The sites selection of optical ground stations (OGSs) in satellite-ground laser communications and the effects applied two types of diversity schemes are examined quantitatively. The existence of interception of the laser beam by clouds, which causes communication quality degradation is judged using the dot values of meteorological satellite images ...

Optical System in Laser Inter-Satellites Communication
Advanced Materials Research, 2014We know that Inter-satellites communica-tion is a very important to us.However, real global coverage can only be achieved by satellite systems. Satellites communication is the most important mean of the communication network. The traditional satellites communication and inter-satellites links are built by microwave.

Lasers Offer Satellites Better Ways to Communicate
Physics Today, 1968What happens to the wavefront of a beam of coherent light as it is propagated through the atmosphere? The question has become one of vital interest to space scientists, and is answerable now that we can study, for the first time, light sent out into space by lasers, as well as that originating from an external source such as a star.
