Outline
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
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.
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

Outline
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).
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.

Functional Division ofADM 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.

Alternative Dissemination Methods (ADM)Progress Report
Current Activities:– Coordinate the NOAA ADM activities and support GEO-Netcast
development NOAA ADM Activities
– Developing a mobile demonstration of ADM Center• Demo status: Practice demos complete; S/W for ADM Control Center
complete; Scripts for demo and PowerPoint charts completed• Demo scheduled for September 2006
– Prototype Development• The Broadcast Management Center (BMC) consists of the ADM
Control Room Software necessary to produce the ADM Broadcast Data Stream
• The Network Management Center (NMC) consists of hardware (with its attendant controller software) to modulate the message bits into communications symbols suitable for transmission over satellite, internet, or dedicated landline
– Application of ADM to GEO-Netcast• Architectural-level concepts have been created to show how all
components of ADM support GEO-Netcast• Coordination with GEO-Netcast continues
Alternative Dissemination Methods (ADM)ADM Prototype
Status of ADM Prototype– ADM Broadcast Management Center– Updated the User Interface Control Panel
• Updated the Priority, Queue, and Channel controls so the administrative user can control each product
• Created an interface to allow the ADM administrator to start and stop the transmission of the scheduled items
• Created an interface to display the schedule based on the administrator selected Queue
– ADM Network Management Center• IP Encapsulator and Modem systems were received in July,
and set-up and integration continues

Alternative Dissemination Methods (ADM)Application of ADM to GEO-Netcast
Proposed Plan:– Demonstrate ADM benefits to the NOAA mission and IGDDS– Explain how ADM can serve as the basis for the NOAA GEO-
Netcast system– Prove ADM is a subset of GEO-Netcast, and in no way exceeds
the requirements of GEO-Netcast
Status of “Application of ADM to GEO-Netcast”– GEO-Netcast architecture and programmatic history have been
reviewed.– Briefed the NOAA GEO-Netcast program manager on ADM– Actions related to GEO-Netcast:
• Demonstrate that the scope of NOAA ADM fits within GEO-Netcast
Alternative Dissemination Methods (ADM)Application of ADM to GEO-Netcast (continued)
Broadcast Format overview– Briefing on ASTC (Advanced Television Systems Committee)
video standard to NESDIS was completed– Briefing on EUMETSAT ADM (EUMETCast) to NESDIS
completedFuture ADM considerations
– Continue to brief the status of the NOAA ADM project– Propose a method by which the NOAA ADM can be interfaced
with the EUMETSAT ADM– Continue to support GEONETcast– Receive EUMETcast C-band broadcast in Chantilly VA, process it
using the ADM Prototype, and redistribute it to NESDIS Suitland via Internet.
CONCLUSION
Future ADM considerations– It has been decided that GEO-NETCast will be phase one of
ADM.– Future planning and funding for GEO-NETCast will be subject to a
successful demonstration in FY 07.
Status of “EUMETCast to NOAA ADM” transition plan for users in South America – NOAA continues to evaluate the use of ADM to support
environmental data users in Central and South America.– NOAA has not reached a definitive solution.
