Reuniwatt, especialista en predicci\u00f3n de cobertura nubosa y pron\u00f3stico de irradiancia solar, participa en el proyecto SOLiS. Aprovechando su experiencia en predicci\u00f3n de nubosidad, la empresa contribuye al avance de las comunicaciones \u00f3pticas por sat\u00e9lite \u2014 una tecnolog\u00eda clave para lograr una transferencia de datos ultrarr\u00e1pida y segura entre la Tierra y el espacio. Nuestro trabajo fue presentado en un art\u00edculo reciente de Bernard Grollier en Les Echos<\/em>, publicado el 17 de julio de 2025. Aqu\u00ed compartimos algunos aspectos destacados y ofrecemos una visi\u00f3n general del trabajo de Reuniwatt en comunicaciones satelitales. Puede leer el art\u00edculo completo en Les Echos<\/em> online<\/a><\/p>\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 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 Para saber m\u00e1s:<\/p>\n<\/div><\/div><\/div>La experiencia de Reuniwatt impulsa las comunicaciones satelitales seguras<\/h2>\n
