Paper Abstract

With the increasing need for higher data rates on small LEO spacecraft, highly compact laser communication systems are required to overcome the limitations in the downlink channel. The Optical Communication Systems (OCS) group at the German Aerospace Center (DLR) has been working on the program OSIRIS (Optical Space Infrared Downlink System) since 10 years. The 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 experiments and developments to demonstrations of relevant technologies. The range of developments and demonstrations covers an OSIRIS application on CubeSats with a demonstration in 2018, as well as very high data rate applications in the scope of the 3rd OSIRIS generation with up to 100 Gbps. These developments are the basis for scientific measurements on the channel characteristics and new applications and technologies in space. In the process towards an industrial application, OSIRIS is also involved in standardization activities in the framework of CCSDS.

This paper will give an overview of scientific missions and developments in the OSIRIS program and give an outlook on the development path ahead.
