  • For the first time, a signal from the DLR terminal OSIRISv1 was received on a NICT ground station in Japan.
  • OSIRISv1 was developed by the DLR Institute for Communication and Navigation and launched in 2017 on the “Flying Laptop” satellite in cooperation with the Institute for Space Systems (IRS) at the University of Stuttgart.
  • Optical communication systems that use laser beams for data transmission make it possible to significantly increase the data rates between satellites and ground stations.

COLOGNE, Germany (DLR PR) — The resolution of cameras and other sensors on earth observation satellites is increasing steadily. This leads to ever-increasing amounts of data that are still transmitted to earth using radio systems today. The data connection between the satellite and the earth limits the capabilities of the systems.  With optical communication systems that use laser beams for data transmission, a significant increase in data rates is possible. Numerous images can be transmitted with high resolution.

FRIEDRICHSHAFEN, Germany (Airbus PR) – Airbus is bringing another experimental system to the International Space Station (ISS) in the form of the photobioreactor (PBR). The PBR, developed by the University of Stuttgart and built by Airbus on behalf of the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR), is designed to convert part of the CO2 extracted by the ‘LSR’ Life Support Rack on board the ISS into oxygen and biomass, which could help to save valuable resources during future long-term missions into space.
