SatNEx IV Satellite Network of Experts IV

  • Status
  • Status date
  • Activity Code

The key objectives of the SatNex IV Network of Experts can be summarized as:

  • Early identification, exploration and scientific assessment of promising new R&D avenues for satellite telecom networks for possible injection in ESA’s R&D programs;
  • Detection and preliminary assessment of promising terrestrial telecommunication technology spinning into space telecom applications;
  • Enhanced cooperation between the European/Canadian industry and research institutions on telecom satellite applied research subjects of common interest.

ESA will ensure the transfer of results to European and Canadian industry and international standardisation bodies fostering Intellectual Property (IP) protection when deemed necessary.
