GEONETCastThe EUMETCast ContributionDelivering Operational Services to Users
GEONETCast Concept • Established in the GEO context to provide a dissemination component of the GEOSS • Utilises existing data dissemination infrastructure provided by environmental satellite operators • Provides environmental satellite and in-situ data and products to users on a global, operational basis • Lead organisations • EUMETSAT • NOAA • WMO
GEONETCast Concept • An operational GEONETCast Implementation Group has been established • Composed of the lead organisations with potential involvement of other contributors; • Reports to the GEO Architecture and Data Committee; • Points of Contact are: • GEO POC: Linda.Moodie@noaa.gov • EUMETSAT POC: Mike.williams@eumetsat.int • NOAA POC: Richard.Fulton@noaa.gov • WMO POC: dhinsman@wmo.int
GEONETCast Components • Based on existing dissemination infrastructure: • EUMETCast • Data Providers/Sources: • EUMETSAT and its Satellite Application Facilities (SAFs) • NOAA • National Meteorological Services (NMSs), ESA, NASA, EC/VITO ….. • Other data providers • Users: • Global User Community
EUMETCast Overview • EUMETSAT’s Broadcast System for Environmental Data • A multi-service dissemination system based on standard Digital Video Broadcast (DVB) technology • Using commercial telecommunication geostationary satellites to multicast files (data and products) to a wide user community • EUMETCast is now available for use by Global Earth Observation System of Systems (GEOSS), the European Global Monitoring for Environmental and Security (GMES) initiatives and other environmental data providers • EUMETCast is also a EUMETSAT contribution to the Integrated Global Data Dissemination Service (IGDDS), a component of the World Meteorological Organization Information System (WIS)
EUMETCast Technical Approach & Standards • Generic, multi-mission dissemination systems based on standard DVB multicast technology • Uses commercial broadcast channels on TV, DTH telecommunication satellites • Off-the shelf, commercially available reception equipment • IP over DVB standard coding • Transparent transfer of files, i.e. files received exactly as sent • Use of standard formats/encoding - XRIT, BUFR, GRIB, HDF … • Secure access control at individual file and group of Users level • Open, flexible, scalable architecture
EUMETCast User Reception Terminal • Antenna/feed/LNB • Antenna size depending on Ku/C-Band and signal strength (Ku-Band typically 0.8 to 1.2 m, C-Band 2.4 m) • Standard digital TV LNB • DVB Receiver Cards used/recommended • Technisat SkyStar2 • BroadLogic V@box 2030 • Pentamedia Pent@value • Workstation • Standard / state-of-the-art PC (with USB port) • Software • Operating Systems: Windows and Linux supporting • EUMETCast Client S/W TelliCast (supporting processing, monitoring and logging of received data) • Additional Support S/W (decompression, file transfer agents, …)
EUMETCast User Reception Terminal Cost DVB Standard Hardware LNB Ku-/C-band & Satellite Dish 200/1500 EUR DVB PCI Card 100 EUR DVB Multicast Client Software 60 EUR EUMETCast Key Unit (EKU) 40 EUR PC, Hard Disk, Ethernet 1000 EUR 1.400/2700 EUR

EUMETCast User Community • Over 1700 EUMETCast User stations deployed • Approximately 50 new User stations are added per month • 320 institutional Users in Europe (NMSs, Institutes, Research, Commercial) • 850 private/individual Users in Europe • 110 Users outside Europe, nearly all institutional: • 80 in Africa • 16 in the Middle East • 5 in the US • 2 in South America • 3 in Russia • 2 in Asia – China and Uzbekistan • Users like the one-stop-shop approach • All the currently deployed stations are ready to acquire GEONETCast datastreams/products.
GEONETCast Demonstration • Is already running delivering Met-8, GOES and EUM & NOAA-sourced products to South America • Datastreams will be added addressing other applications/User communities • Consists of a merged stream of NOAA/US and EUMETSAT/Europe sourced data and products • Scope of the demo includes the definition of the User Terminal required for data acquisition and basic data processing • Suitable processing s/w packages include: • 2Met! - GeoSatSignal - MSG Data Manager • Cinesat - GRIB Viewer - HRPT Manager • Messir - HDF Viewer - ATOVS Reader • MEOS - Timestep - XRIT2PIC • Demo does not currently cover provision of User Terminals, or upgrades to existing User Terminals • Datastream/product list has been compiled by NOAA and EUMETSAT
