Executive Summary

COTS components are gathering more and more interest from satellite developers thanks to their lower cost and ease of procurement as compared to space qualified ones. A number of studies to evaluate the possibility of COTS use in space systems are under way: automotive and consumer electronic devices are evolving fast and their innovative solutions can have a beneficial effect on space systems. This paper will focus on the analysis of the IrDA (Infrared Data Association) protocol and on the possibility to employ it to exchange data between the sub-systems of a satellite.
