Reuniwatt is excited to announce its participation in the upcoming IEEE International Conference on Space Optical Systems and Applications (ICSOS 2025), taking place from October 28 to 31 in Kyoto, Japan. This event gathers the brightest minds and innovators in space optical communication, providing a perfect platform to present the latest advances in assessing atmospheric impacts on Free Space Optical (FSO) communications.
Presenting Cutting-Edge Research in Kyoto
At ICSOS 2025, Reuniwatt will be onsite as an exhibitor, and present our latest poster Relevance of the NWC SAF Cloud Type product to assess the impact of clouds on Free Space Optical Communication.
The performance of FSO links is critically dependent on atmospheric conditions, with clouds posing the most significant threat to link availability. Co-authored by Nicolas Sébastien, Olivier Liandrat, and colleagues, the study explores how satellite-derived cloud classification can predict and mitigate the risks of cloud-induced attenuation on FSO links. The Cloud Type classification provided by the NWC SAF (Nowcasting Satellite Application Facility) software can be used to infer the potential impact of clouds on OGS operations worldwide. However, the relatively coarse spatial resolution of satellite imagery introduces uncertainty. To evaluate the reliability of this approach and improve its precision, we present an analysis linking each Cloud Type with in-situ measurements of cloud-induced attenuation. Our study blends satellite data with ground-based infrared imaging with Sky InSight™ to enhance the reliability of cloud impact assessments. Furthermore, our findings confirm that the Cloud Type product, despite its limitations, offers valuable insights into the risk profile of FSO link disruptions. Our result also confirms that site surveys would benefit from in-situ measurement campaigns to refine the analysis of atmospheric conditions.
