Satcoms 2020 R&D Challenges - May 10, 2011

It is our pleasure to host this distinguished lecture by Prof. Riccardo De Gaudenzi, European Space Research and Technology Centre (ESTEC). The lecture will be followed by a reception. Please feel free to forward this invitation.

Abstract:  In this paper we will depict possible application scenarios for future satcom networks, together with the associated key challenges as well as critical techniques and technologies which in the authors’ opinion show enough potential to justify their development in the coming years.

Some initial estimates of the potential benefits of the introduction of the different technologies listed above will be shortly illustrated. It will be shown that timely development of these technologies can make challenges like the Terabit/s satellite becoming true as well as place the satellite technology in a much stronger position for massive multimedia (video) downloading to large communities.

In the authors’ opinion the identified systems and payload architectures, techniques and technologies shall be timely developed to ensure that satellite offer will be able to keep its attractiveness in complementing the terrestrial networks. ESA has initiated studies and prototyping activities in most of the identified areas but the momentum shall grow to ensure that the technology maturity will be at the right level when the commercial request will emerge. The preliminary results of this presentation is related to the application scenarios and the performance impact for the various techniques and technologies are expected to trigger the discussion and support decision makers to choose which are the most promising R&D lines to invest.

Prof. Riccardo De Gaudenzi  was born in Italy in 1960. He received his Doctor Engineer degree (cum Laude) in electronic engineering from the University of Pisa, Italy in 1985 and the PhD from the Technical University of Delft, The Netherlands in 1999. From 1986 to 1988 he was with the European Space Agency (ESA), Stations and Communications Engineering Department, Darmstadt (Germany) where he was involved in satellite telecommunication ground systems design and testing. In 1988, he joined ESA’s Research and Technology Centre (ESTEC), Noordwijk, The Netherlands where since 2005 he is Head of the RF Payload and Systems Division. The division is responsible for supporting the definition and development of advanced satellite system, subsystems and related technologies for telecommunications, navigation and earth observation applications. In 1996 he spent one year with Qualcomm Inc., San Diego USA, in the Globalstar LEO project system group under an ESA fellowship.  His current interest is mainly related with efficient digital modulation and multiple access techniques for fixed and mobile satellite services, synchronization topics, adaptive interference mitigation techniques and communication systems simulation techniques. He actively contributed to the development and the demonstration of the ETSI S-UMTS Family A, DVB-S2 and DVB-SH standards. From 2001 to 2005 he has been serving as Associate Editor for CDMA and Synchronization for IEEE Transactions on Communications. He is co-recipient of the 2003 and 2008 Jack Neubauer Memorial Award Best Paper from the IEEE Vehicular Technology Society.
