Data Collection System
• Meteosat-7 located at 0° supporting the Prime DCS service– 33 regional channels, close to maximum
utilisation– 33 international channels co-ordinated by CGMS
• Meteosat-5 located at 63° E supporting the IODC DCS service from the 1st March 2005– 3 international channels co-ordinated by CGMS

IODC DCS
• Three International Channels - I8, I9, I11 reserved for regional use by IODC, to be formally approved by CGMS in September 2005
• Uses redundant equipment in the MTP Ground Station in Fucino, Italy to receive the data
• Data processed and disseminated by the EUMETSAT central site

DCP Data Dissemination
• For the 0° Service– GTS– Internet - ‘push’ and ‘pull’– EUMETCast– DCPRTU
• For the IODC Service– GTS– Internet - ‘push’ and ‘pull’

EUMETCast Overview
• Generic, multi-mission dissemination system based on the standard DVB multicast technology
• Use of commercial telecommunication satellites
• Allowing use of off-the shelf, commercial, inexpensive equipment
• DVB/MPEG-2 based transport for carrying IP datagrams
• Use of a set of broadcast satellite forward channels (no return channel)
• Components:– Data providers
– Service management provider (EUMETSAT)
– Uplink service provider
– Turn around service provider(s)
– Satellites
– (Reference) Reception stations

IODC DCS Applications
• University of Hawaii - Sea Level Centre:– 8 platforms are located in the Indian Ocean,
they report hourly via Met-7– They will be re-allocated to Met-5 and increase
reporting frequency to every 15 minutes– Data Dissemination mechanism - GTS +
Internet (pull)– They plan to add 1 new platform in March

System Limitations
• Limited international channels available– Five more channels could be used with CGMS
agreement
• No ground segment redundancy until MSG-2 is successfully commissioned
• IODC dissemination mechanisms are currently limited to GTS and Internet

Page 16EM-EEW Jakarta 14 - 18 March 2005
Future Planning
• MSG-2 launch and commissioning
• Space segment relocations
• Meteosat-7 will replace Meteosat-5 at 63°E to continue the IODC Service until the end of 2008

System Issues
• Following the successful commissioning of MSG-2, the Fucino Ground Station equipment will support the IODC DCS with redundancy
• Meteosat-7 has a battery problem which may mean up to a 2 hour outage during the satellite eclipse season - Mar/April and September/October - under investigation
