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

Page 8EM-EEW Jakarta 14 - 18 March 2005

DCP Data Dissemination

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

• For the IODC Service– GTS– Internet - ‘push’ and ‘pull’

Page 9EM-EEW Jakarta 14 - 18 March 2005

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

Page 15EM-EEW Jakarta 14 - 18 March 2005

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
