Setting Standards in Communications

Global Connectivity for People and Machines

The global provision of broadband Internet access is a major challenge. Outside urban areas, current coverage is unsatisfactory even in Europe, but further expansion of terrestrial networks is increasingly uneconomical. Solutions are being sought worldwide. Constellations of several hundred or thousand satellites are receiving the most attention. Also in aviation and maritime transport, the digitization of radio systems offers great potential that needs to be developed. Here, the introduction of a standard developed under the leadership of DLR is approaching. In satellite-based earth observation, the volume of data now exceeds the capacity of radio transmission systems. Standardized optical methods promise a solution here.

Our contributions

System concepts for broadband coverage via
geostationary VHTS and LEO constellations
With new, predominantly satellite-based solutions, we are closing the gaps in global broadband coverage for the population and increasing the reliability and resilience of data networks for Industry 4.0, smart mobility and civil security.

New communication standards for aviation and maritime traffic
By defining new digital communications standards, we are enabling the further growth of air, sea and rail traffic, as well as the increasing autonomy of the systems in use, while at the same time increasing security.

Data repatriation from space
With the development of optical communication terminals and highly efficient radio links, we are creating solutions for transporting observation data from satellites and stratospheric platforms to ground stations.

Cube4CubeSat / CubeLCT

OSIRIS4CubeSat zielt im Gegensatz zu den anderen OSIRIS-Nutzlasten nicht auf eine weitere Steigerung der Datenrate, sondern auf ein hochkompaktes Systemdesign, das es erlaubt, optische Kommunikation selbst auf Kleinstsatelliten wie CubeSats einzusetzen.

CubeISL

OSIRISv3 stellt eine weitere Stufe der Weiterentwicklung von OSIRIS zu höheren Datenraten dar. Das Terminal verfügt nun über eine eigene Ausrichteeinheit. Die Datenrate kann damit auf bis zu 10 Gbit/s gesteigert werden.
