A Review on Inter-satellite Link in Inter-satellite Optical Wireless Communication

Journal of Optical Communications, 2017
AbstractIn this paper, inter-satellite optical wireless communication (IsOWC) system is proposed, one of the imperative utilizations of free space optics/wireless space optics (FSO)/WSO innovation. IsOWC frameworks give a high bandwidth, small size, small weight, low power and minimal effort different option for present microwave satellite frameworks ...

The optics mechanical module for inter-satellite link

SPIE Proceedings, 2016
Inter-satellite link (ISL) is a system of several satellites, which encircle the earth and spaced at a fixed distance from each other - of about 3000 kilometers. The optical-mechanical module (MOM) for the ISL is designed to transmit data over long distances in a small range of angles.

Homodyne BPSK Based Optical Inter-Satellite Communication Links

24th AIAA International Communications Satellite Systems Conference, 2006
Summer 2007, Tesat will verify laser communication terminals based on homodyne BPSK (binary phase shift keying) in-orbit. A 5.625 Gbps LEO-LEO laser communication link, established between the German satellite TerraSAR-X and the US satellite NFIRE, shall demonstrate the performance and advantages of laser communication.
