“…The typical availability required by the satellite operators for the feeder link is 99.9% [3,4]. An availability of 99.7% will also be analyzed here as an opportunity to decrease the number of OGSs, and therefore the overall system cost, while still providing an acceptable end-user quality of experience.…”

“…Based on market analysis [2], the targeted capacity of next-generation high-throughput satellites should reach 1 Tbit/s, which is one order of magnitude higher than what is currently provided by state-of-the-art satellites (e.g., Ka-Sat or Viasat 1). For such capacity, recent system studies [3,4] demonstrated that at least 30 Q/V band gateways spread over Europe are necessary to provide connection between the Earth and the satellite, the so-called feeder link. This increases the complexity of the frequency coordination that aims to control the intersystem interference.…”

“…As depicted in Fig. 1, the obstruction of the optical signal by clouds [6] necessitates the design of a network of geographically distant optical ground stations (OGSs) to reach the typical link availability of 99.9% required by satellite operators [3,4]. We call this network the optical ground station network (OGSN).…”

High-data-rate space-to-ground optical links are anticipated to be an alternative to radio-frequency spectrum congestion for the next generation of highthroughput geostationary satellites. An affordable site diversity system based on several optical ground stations (OGSs) and an optical fiber network is necessary to overcome cloud obstruction of the feeder link. In this paper, we report three promising sets of OGSs in the vicinity of existing ingress and egress points of a selected pan-European optical fiber network. These OGS networks are optimized for reaching at least 99.9% feeder link availability while minimizing the overall cost of the system. For the first time, the optical fiber network between OGSs is optimized using existing high-data-rate fiber links to limit its expense. The resulting cost estimates for each OGS network highlight the need to define a new cost model considering optical feeder link specificity. In addition, the link availability is simulated using a 2 year cloud mask data bank, taking into consideration practical cloud blockage forecasting duration and assuming optical transmission through thin ice clouds.

One of the key performance targets on the European Commission's Digital Agenda is to provide at least 30 Mbit/s broadband coverage to all European households by 2020. The deployment of existing terrestrial technologies will not be able to satisfy the requirements in the most difficult-to-serve locations, either due to a lack of coverage in areas where the revenue potential for terrestrial service providers is too low, or due to technological limitations that diminish the available throughput in rural environments. In this paper we investigate a hybrid broadband system combining satellite and terrestrial access networks. The system design and the key building blocks of the intelligent routing entities (referred to as intelligent gateways) are presented. To justify the hybrid broadband system's performance subjectively, lab trials have been performed with an integrated multiple access network emulator and a variety of typical multimedia applications that have varying requirements. The results of the lab trials suggest that the Quality of Experience is consistently improved thanks to the utilisation of intelligent gateway devices, when compared to using a single access network at a time.
