Reuniwatt, specialist in cloud-cover prediction and solar irradiance forecasting, is taking part in the SOLiS project funded by France 2030. Leveraging its expertise in cloud prediction, the company contributes to advancing satellite-based optical communications \u2014 a key technology for achieving ultra-fast, secure data transfer between Earth and space. Our work was presented in a recent article by Bernard Grollier in Les Echos p<\/em>ublished on July 17, 2025. Here we share some highlights and provide an overview of Reuniwatt’s work in satellite communications. You can read the full Les Echos article<\/a> online.<\/p>\n

Reuniwatt\u2019s cloud expertise powers secure satellite communications<\/h2>\n

The European Commission\u2019s VERTIGO project, and CNES\u2019s CO-OP, DYSCO, and now SOLiS projects have benn focusing on research and development of free-space communications, seeking to demonstrate very-high-data-rate space optical links transmitting through the atmosphere. Reuniwatt’s unique cloud cover expertise has made the company a trusted partner in next-generation satellite communication projects. \u201cSatellite communication, with data transmission speeds reaching up to 1 terabit per second, represents the market of the future,<\/em>\u201d says Nicolas Schmutz, Founder and CEO of Reuniwatt. Laser beams used to transfer data between space and the ground are significantly disrupted by dense cloud layers. Having accurate, expert knowledge of cloud formations allows operators to schedule laser transmissions at the optimal moment.<\/p>\n

Since 2013, Reuniwatt has collaborated with the Saint-Exup\u00e9ry Research Institute and participated in Airbus Defence and Space\u2019s CO-OP project, which tested ultra-high-speed optical links between Earth and geostationary satellites. With SOLiS led by Thales Alenia Space, Reuniwatt is entering a new phase: helping develop an optical terminal that will enable real-time, secure communication between ground stations in Nice and Cyprus.<\/p>\n

SOLiS: Building the future of high-speed space data networks<\/h2>\n

The SOLiS project \u2014 for Service Optique de Liaisons Spatiales S\u00e9curis\u00e9es (secure optical space link service) \u2014aims to demonstrate the technical and economic viability of an optical communications service relying on geostationary satellites. It will evolutionize data transfer by interconnecting multiple ground stations through satellites, ensuring stable, high-speed communication even when traditional fiber networks fail. Reuniwatt\u2019s role is critical: by predicting cloud conditions above each station, its technology will help optimize laser routing and maintain uninterrupted connectivity. The Greek satellite carrying the SOLiS optical terminal is scheduled for launch in 2029, marking a major milestone in secure optical space links.<\/p>\n
