GEONETCastThe EUMETCast Contribution

Delivering Operational Services to Users

GEO User Interface Committee Meeting, Ottawa, 5 – 7 September 2006 Page 2

• 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

GEO User Interface Committee Meeting, Ottawa, 5 – 7 September 2006 Page 4

• 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

GEONETCast Components

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)

GEO User Interface Committee Meeting, Ottawa, 5 – 7 September 2006 Page 6

• 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 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
