3. Background: What is ADM? NOAA provides environmental data to a variety of environmental users –GOES and POES data as well as hydro-met data Primary dissemination method is currently Direct Readout –Transmitted via government weather satellite NOAA sees a need for alternative methods of dissemination –Direct Readout has insufficient capacity –European ADM system is currently deployed Meteosat data transmitted over the “Hotbird” commercial communications satellite

4. Background: What is ADM? Alternative to traditional NOAA dissemination methods ADM is the dissemination of multi-mission satellite data (includes sounder and imagery) from NOAA, and (potentially) EUMETSAT and JMA satellites. Dissemination methods: –Internet (such as FTP request) –DOMSAT to ADM User Terminal –Dedicated Landline ADM is NOT Direct Readout.

5. Purpose of ADM Study Create a high level design and architecture for ADM –Design Communication Trunks –Design ADM User Terminal Design a data dissemination system for environmental data other than Direct Readout. –Cost effective architectures –Cost effective ADM user terminal

7. ADM Tasks and Approaches Considered 1.Communication Trunks –Research and recommend a method of transmitting data, point to point, or point to multi-point. –Internet »FTP services –DOMSAT (Domestic Satellite, Commercial Communications Satellites) »Utilize ADM Common User Terminal –Dedicated Fiber Optic Cables (Landlines) 2.ADM User Terminal –Research and Recommend a user terminal that will work with many commercial communications satellites and distribution systems (including commercial satellites distributing the ADM broadcast).

8. Results Summary Internet distribution is not the only solution for ADM –Commercial Communications Satellites also have a role in ADM Conformance to DVB-S (Digital Video Broadcast-Satellite) provides the lowest system cost –Conformance to DVB-S needed for low cost user terminal cost Standard data rates for DVB-S service –16.3 to 47.2 Mbps, dependent on EIRP and Bandwidth available ADM user terminal cost about $2,200 (includes antenna, PC and software) –Insertion of DVB-S PCI cards in desktop computers (PCMCIA Laptop card is not available) Commercial Communications Satellite is the only solution for remote areas –Highest Cost is lease of commercial satellite transponders.

13. Functional Division of ADM Broadcasting System The ADM Management Center must be divided into two functions: –Broadcast Management Center (BMC) Determines which programs will be on the broadcast, and their order. Operated by NOAA NESDIS Receives programming from multiple sources Assembles the Broadcast and sends it to the NMC –Network Management Center (NMC) Routes data Formats data Transmits data Contains communications hardware for transmission –Satellite dishes, modems, amplifiers

Internet Connection for ADM User Ev1servers.net (formerly RackShack.net) –Web server company that specializes in high bandwidth servers –$89 per month (ref: 9 Oct 2003 website) –700 GB transferred / month Calculate ADM transfer rate required with the following assumptions: –1 hit per second ; 200 kB per hit –Yields: 501.59 GB / month = 6,019.1 GB / yr. Cost not an issue for Internet connection –Availability of Internet connection to ADM User is an issue –Ability of Internet connection to support 10.5 Mbps streaming data rate is an issue. –Reliability of Internet connection is an issue.
