The Optical Space InfraRed DownlInk System (OSIRIS) program started with the development of optical communication payloads for the Flying Laptop and BiROS satellite, which are already in orbit. The program covers a very broad range from scientific developments to demonstrations of relevant technologies. The range of thses developments and demonstrations covers an OSIRIS application on CubeSats, as well as very high data rate applications. These developments are the basis for scientific measurements on the characteristics and applications of technologies in space. OSIRIS is also involved in standardization activities in the framework of CCSDS to progress towards industrial appliation.
