  1. Current Framework • Introduction (background) • Operational requirement • Technical description (satellite-based communication system) • Architecture • technical features • Multiple access technologies • Transmission technologies • Modulation Methods • Services • Two-way: data collection and exchange • broadcasting: data distribution • Possible use in WIS/GTS • Connected NC to DCPC • GISC/DCPC distributing data to NCs and users • Guide on using satellite-based data communication service

  2. Guide on using satellite-based data communication service • describe the way to use the services • How to connect to the existed system • How to distribute data (connected to a service provider, distributing data through broadcasting service) • How to collect data (connected to a data-broadcasting system) • not to describe the way to build a data broadcasting system

  3. Questions • Broadcasting service • Usage of satellite-based broadcasting services in GTS and WIS • Routine data (real-time data) • Subscription data • Ad-hoc data request • Available satellite-based broadcasting services • DWDSat, EUMETCast, FUNYUNCast, RETIM Africa, SADIS, ……. • service name • provider, operator • coverage • provided data • contacts • The way to use satellite-based broadcasting services • Providing data to users • Collection data • Two-way system • different system, different technology • National communication, unavailable outside • Question: • Only focus on satellite-based data broadcasting service ? • Or, include two-way system: one existed system?
