ABSTRACT
Any Communication system needs a medium to operate. Satellite communication and optical communication are two different methods of communication. Satellite communication uses a satellite as a repeater between two points that exchange information, here medium is air and information is passed as electromagnetic waves. Satellite Communi ....etc

ABSTRACT
Laser communications offer a viable alternative to RF communications for intersatellite links and other applications where high-performance links are necessity. High data rate, small antenna size, narrow beam divergence, and a narrow field of view are characteristics of laser communication that offer a number of potential advantages for system design.

Free space optical communications is a line-of-sight (LOS) technology that transmits a modulated beam of visible or infrared light through the atmosphere for broadband communications. In a manner similar to fiber optical communications, free space optics uses a light emitting diode (LED) or laser (light amplification by stimulated emission of radiation) point source for data transmission. However, in free space optics, an energy beam is collimated and transmitted through space rather than being guided through an optical cable. These beams of li ....etc

Overview

Imagine a technology that offers unsurpassed reliability and

high-speed connectivity. A technology that can be installed globally is

easy to deploy, license-free and offers a fast, high ROI. That

technology is free-space optics (FSO).

Free Space Optics (FSO) communications, also called Optical

Wireless (OW) or Infrared Laser, refers to the transmission of

modulated visible or infrared ....etc

Free Space Laser Communications

Lasers have been considered for space communications since their realization in 1960. However, it was soon recognized that, although the laser had potential for the transfer of data at extremely high rates, specific advancements were needed in component performance and systems engineering, particularly for space-qualified hardware. Advances in system architecture, data formatting, and component technology over the past three decades have made laser communications in space not only a viabl ....etc

In summer 1977, ESA placed the first technological study contract in the domain of intersatellite optical links. Now, twenty years later, a major milestone has been reached with the SILEX laser terminals having been flight tested for integration with their host spacecraft. At the same time, ESA is preparing itself for a new challenge: the potential massive use of optical cross links in satellite constellations for mobile communications and global multimedia services. This is an opportune moment to look back at the past twenty years of ESA effor ....etc
