YODA
Two patrol smallsats
To address new threats and unfriendly actions in Space, France has a goal: to monitor Space, from Space. Against this backdrop, CNES awarded HEMERIA the YODA project (French acronym for “eyes in orbit for an agile demonstrator”), the aim of which is to design and supply a demonstrator for two reconnaissance smallsats in geostationary orbit, to protect French military satellites from suspicious, or even hostile maneuvers.
