Abstract
Optical communications (OC) is an emerging transformative technology for scientific, commercial, and defense applications. Compared to radio-frequency (RF) communications, it can offer higher bandwidth, lower power consumption, and reduced size and mass of transceivers. Narrow, directed beams of light, OC can in principle increase link security and enable optical quantum communication, which provides absolute physical security. Free-space optical satellite networks will employ both satellite-satellite and satellite-Optical Ground Station (OGS) optical links. Optical Communication terminals (OCT) on-board a satellite have to comply to volume and energy limitations, restricting the available optical power and optical system parameters. In this paper, we perform an optical link design trade-off between an OGS and a Low Earth Orbit (LEO) satellite. We study the feasibility of utilizing Skinakas Observatory in Greece as an OGS, for realistic OCT specifications and based on the criterion of link budget. We model an optical downlink and compute the results for various critical parameters of the OCT. Our results confirm the feasibility of such a link for optical communication purposes.
