1. Space Segment
The following satellite operators providing the current C, Ku and Ka-band Satellite Constellations suitable for DVB-RCS S and S2 scenario covering South and Sub-Saharan Africa are illustrated in Figure 1: Intelsat (A), PanAmSat (B), SES-NewSkies (C) and Eutelsat (D). Those Operators provide regional or global and spot beam coverage via Geostationary Earth Orbits (GEO) satellites.
2. Ground Segment
The DVB-RCS VSAT network has been designed to minimize the cost of scaling a broadcast, broadband and multimedia access via few HUB solutions from terminal populations as small as several hundred SIT units to tens or even hundreds of thousands of simultaneously logged-on SIT units in urban and rural or remote areas, see Figure 2. The DVB-RCS network for mobile maritime, land (road and railway) applications is presented in Figure 3. Satellite DVB-RCS via VSAT HUB with C (4-8 GHz), Ku (12-18 GHz) or Ka-band (27-40 GHz) antenna system interfaces and extends the Terrestrial Broadband, Video Broadcasting, UMTS/GPRS (Universal Mobile Telecommunications System/General Packet Radio Service), Asynchronous Transfer Mode (ATM), Terrestrial Telecommunication Network (TTN), Internet Service Providers (ISP), Cellular, Private and Public Networks, Virtual Private Networks (VPT), Fiber Optical Networks (FON) and any other civilian corporate or military networks with corresponding satellite connection to SIT units or Remote terminals and enables the following major services:
