Space Optical Links for Communication Networks

  title={Space Optical Links for Communication Networks},
  author={Alberto Carrasco-Casado and Ramon Mata-Calvo},
Future spacecraft will require a paradigm shift in the way the information is transmitted due to the continuous increase in the amount of data requiring space links. Current radiofrequency-based communication systems impose a bottleneck in the volume of data that can be transmitted back to Earth due to technological as well as regulatory reasons. Free-space optical communication has finally emerged as a key technology for solving the increasing bandwidth limitations for space communication…

OSIRIS Payload for DLR's BiROS Satellite
Direct optical communication links might offer a solution for the increasing demand of transmission capacity in satellite missions. Although direct space-to-ground links suffer from limited
Preliminary results of Terabit-per-second long-range free-space optical transmission Experiment THRUST
Future Very High Throughput Satellite Systems (VHTS) will perform at several Tbit/s throughput and thus face the challenge of limited feeder-link spectrum. Whereas with conventional RF feeder links
Design status of the development for a GEO-to-ground optical feeder link, HICALI
Concepts and current design status of the HICALI system, which goal is to achieve 10 Gbps-class space communications in the 1.5-μm band between Optical Ground Stations (OGSs) and a next generation high-throughput satellite with a hybrid communication system using radio and optical frequencies, are described.
As telemetry downlink data rates from EO-satellites increase and available radio frequency transmission spectrum narrows, optical data downlinks based on directed modulated laser sources become a
