Paper Abstract

Recent satellites of the European Data Relay System (EDRS) are established with free-space optical (FSO) terminals. Operational FSO links in space are commercially available. Links between ALPHASAT or EDRS-A as GEO terminals and Sentinel LEO terminals are established with TRL 9. However laser links from the satellites through the atmosphere have a low Technical Readiness Level. Starting 2015 an Airborne Optical Communication (AOC) Demonstrator was developed by Hensoldt, which provides Air-to-Space unidirectional communication capabilities over approximately 40000 km distance (Geo orbit) at a data rate of 1.8 Gbit/s at a wavelength of 1064 nm with a laser power of approx. 15 W. The demonstrator was flown on an Airbus A310 aircraft. Successful links with user data streams from Tenerife to the GEO Alphasaat proved the function of AOC.
