New horizon scenarios using the Q/V band technology for satellite constellations

Resumen

This work proposes a market key satellite communication technology that would reduce the cost of satellite communications and improve the actual communication capabilities with a new technology and concept over the state of the art. This is part of the QVBRE (Q/V Band Relay network over EOS) initiative proposed and presented to H2020. This pioneering concept proposed can yield a more reliable and competitive satellite communication technology pushing the European Manufacturers up in the global marketplace. The major goal for QVBRE is the implementation of the communication payload in future Earth Observation Satellites (EOS). This initiative is supported by cutting edge research on different antenna configurations including reflectarrays, reflectors and multi-mode elements, on novel modem architectures using DVB-S2x and new generation waveforms to achieve the actual social and systems communication requirements, on microelectronic for RF circuits, on on-board communication payload computer, and on ground segment for operation and control. This new technology will be able to break actual barriers that can be summarized as to provide high data rates for global coverage with cost-effective architecture, less satellite transmitted power, new markets in Q/V band, small users terminals and lower transmitted power, ISL geometry at Q/V band, and implementation of novel technologies promoting EU industry growing. This paper introduces the innovative concept, new achievable scenarios to support the new concept, the ISL geometry and its challenges, the expected impact with simplified network simulation analysis and preliminary analysis of the antenna system options.
