Ultra High Throughput Multi-Spot Beam Networks
The project is an ESA ARTES 5.1 funded project
The current activity intends to analyze the techniques at the ground segment for broadband GEO satellite services to fixed stations targeting near terabit per second system capacity in the 2020 timeframe.
In order to reach ultra high capacity, these systems shall exploit as much bandwidth as possible in the user links, and dual polarization at the system level.
In addition, higher aggregate capacity can be offered through extensive frequency reuse thanks to increased number of beams coverage. However, increasing the number of beams would result in a beam size in the order of few tenths of degree, therefore in the same order of magnitude of current achievable beam pointing stability. This will cause large fluctuation over time of the beam coverage over the service area so requiring mitigation measures.
Due to regulation constraints, irregular frequency reuse may be necessary. In high traffic areas, hot spots at higher frequencies such as Q/V band may be implemented.
These trends have several major implications. Among them:
