Development history of CMA data dissemination system
l 1998 PCVSAT, in operation – Ku band system , 2Mbps – Cover China and surrounding area – Disseminate conventional data, the file size is less than 2MB. – Over 2400 users in China, 5 users abroad
l 2004 – FENGYUNCast，in operation – C band system, 8.8Mbps – Cover Asia and part of Pacific area – Disseminate FY series satellite data & products – Over 200 users including 18 abroad users – 1 of 3 broadcast system of GEONETCast
l 2006 DVBS，in operation – Ku band system, 8.5Mbps – Cover China and surrounding area – Disseminate conventional data and NWP – Over 700 users in China – It is technical upgrading of PCVSAT and partly take over it.
Initiation of CMACast l 2008 Initiated to build an integrated data broadcast system which is named CMACast. The main objects are: – Improve data dissemination capability and latency – Provide onestop data services. It will broadcast in situ, airborne, and spacebased data instead of three systems
– Increase reliability to ensure continuously – Take over responsibility of FENGYUNCast, DVBS & PCVSAT – Fulfill CMA’s commitments to GEO
l 2008 Exchanged data with EUMETSAT & rebroadcast. l 2010 Device installation and test
– Hardware and software had been installed – Under closeloop test and trial operation – Start operation in 1st quarter next year – FENGYUNCast, DVBS stop operation in 2nd quarter next year
CMA’s onestop data services
CMACast – As succeed of FENGYUNCast it will take over FENGYUNCast’s responsibility to GEONETCast completely.

1. To exchange data with NOAA (GEONETCastAmericans)
Option 1: We only need to configure logical route to link CMA &NOAA. And expand MPLS VPN bandwidth when necessary.
1. To exchange data with NOAA GEONETCastAmericans
Option : There are marine optical cable link ChinaUS. We can setup a direct meteorological data link between CMA and NOAA by rent 2Mb or 3Mb bandwidth from telecommunication company.

CMA had donated 18 sets to abroad user & 2 sets to H.K and Macau. We will upgrade necessary hardware and software for them in free of charge.
SUMMARY CMACast’s advantages
1. Advance DVBS2 technology makes CMACast more powerful, available , reliable.
2. The 70Mbps data broadcast rate can disseminate data 4 times faster than FENGYUNCast and DVBS.
3. Totally 400GB broadcast capability can disseminate In situ, airborne, spacebased data & NWP products to users daily according to user’s authorization level.
4. Onestop service can save user’s cost. One terminal is enough for user to ingest all data.
5. Data exchange & rebroadcast capability make Global village become a real one world.
6. Application software provide choices to users and can help user to utilize data efficiently.
7. ……
CMA’s latest contribution to GEONETCast & user community
2011 Work Plan
lCMA internal user station upgrade – by the end of June
lCMA community user station upgrade – by the end of July
lAsiaPacific user station upgrade – by the end of September
lFENYUNCast, DVBS , PCVSAT close – by the end of this year
