Optical Data Downlinks from OSIRIS on Flying Laptop Satellite

Optical High-Speed Telemetry Downlinks for high data volumes from Earth Observation Satellites in Low Earth Orbit (OLEODL) is currently developing into a future standard in high-speed space communications. The German Aerospace Center (DLR) Institute for Communications and Navigation (IKN) has developed the miniaturized data downlink terminal OSIRIS (Optical Space InfraRed downlInk System) for space-to-ground links over LEO-distances, and has proven its Performance by pre-operational downlinks from the University of Stuttgart Flying-Laptop (FLP) satellite.
