Abstract

The continuous increase of traffic demands for satellite networks motivates the evolution of the telecommunication satellite technology towards wider channels and multiple beam operation with frequency re-use across the coverage. This is made possible by the use of higher frequency bands. Recent research projects 1,2 have investigated multi-beam coverages with more than 200 user beams operated in Ka band, to offer very large data throughputs over Europe. Since 2012, the European Commission project Broadband Access via integrated Terrestrial and Satellite systems (BATS) has explored a similar concept based on a dual satellite solution offering around 302 user beams over EU27 and Turkey, targeting 2020 timeframe, see Figure 1. In all these systems, so as to maximize the user link capacity, the whole civil band allocated to Fixed Satellite Services (FSS) in Ka band (20/30 GHz) is dedicated to the user links. The feeder links thus have to be operated in another band. An attractive option is to rely on Q/V bands (30/40 GHz) to provide the gateway-to-satellite links. Despite the large available bandwidths in Q/V band (5 GHz in each direction), the very large user aggregated bandwidths are required to implement several tens of gateways to provide the necessary capacity.
