  2. INTRODUCTION • EMWIN – • As it is today • Transition to GOES-N,O,P generation • The Third Border Initiative • The GOES-10 Move • Questions?

  3. EMWIN - Today • Description • Functionality • Advantages • Basic architecture • Satellite coverage • Users • Retransmission Providers

  4. EMWIN – TodayDescription • EMWIN -- is a service that allows users to obtain critical weather and certain other information directly from NOAA’s National Weather Service (NWS) in near real time. • Intended to be used primarily by emergency managers and public safety officials who need timely weather information to make critical decisions • However, it can be accessed by anyone with proper equipment.

  5. EMWIN – TodayDescription cont’d • On EMWIN - NWS makes available a 24x7 data feed of current weather warnings, watches, satellite imagery, advisories, forecasts and other products. • NWS data feed disseminated simultaneously over the internet and via the GOES satellite broadcast • Typical information latency: • Alerts & warnings less than 1 minute • Forecasts ~ 2 - 5 minutes • Graphics & imagery ~ 10 – 15 minutes

  6. EMWIN – TodayFunctionality • Data collected from a variety of sources: • NWS Telecommunication Gateway (RTH Washington) • NWS Weather Wire Service (NWWS) • FTP sites • Internet • Data is collected at the EMWIN servers and : • Prioritized into high, mid, and low priority products • Split into 1k packets • Assembled into a 9.6kbs serial data stream

  7. EMWIN – TodayFunctionality cont’d • The Satellite data stream is sent to NOAA Command and Data Acquisition Station (WCDAS) at Wallops, Virginia • Up linked to NOAA satellites (GOES East and West) • Modulation – Dual Frequency Shift Keying (DFSK) • Speed - 9.6 kbps • Frequency - 1690.725 MHz • Approximately 80 megabytes per day • Internet dissemination is also available using Internet unicast (“Byte Blaster”) or File Transfer Protocol techniques.

  9. EMWIN – TodayAdvantages • Receiver equipment and display software is relatively inexpensive and commercially available • L-Band satellite broadcast is virtually “weather proof User equipment is relatively compact and rugged. • Can run on a laptop and use a 1 meter dish • Data-stream is free, repeatable and can be customized for local retransmission. • Large and knowledgeable user community to help monitor performance and answer user questions

  11. Typical EMWIN Satellite User EMWIN Satellite Dish Internet cloud Optional Alarm Controller Receiver Internet access to Byte blaster network To Alarm Units Standard Pentium PC

  12. EMWIN TODAYUSERS - Typical • NWS Forecast Offices and their staff Warning Coordination Meteorologists (WCM’s) • for work with local emergency managers and used in public training • Other countries’ NMHS, e.g. Canada, South and Central America, and Pacific island nations • Media, television and radio stations • Police, fire and EMT Services • Retransmission providers • Schools , amateur meteorologists, EMT’s, storm spotters, storm chasers, Skywarn Network,hobbyists of all ages

  13. EMWIN –TODAYRETRANSMISSION PROVIDERS • Re-broadcasters can relay the data stream as is or filter the data stream and insert local emergency data • VHF (150 mHz band) radio broadcasts • NWS has two systems • Many others provided by co-operative public & private organizations • Can also link with paging systems to send emergency warnings or text • Pacific satellite broadcast • “PeaceSat” satellite operated by University of Hawaii • Formerly GOES-7

  14. Typical VHF Re-transmission System 1690.725MHz 1690.725MHz GOES WEST dish GOES EAST dish Internet or Intranet cloud Broadcast Antenna Receiver Custom local EMWIN Data stream 153.950KHz To Paging Network VHF Transmitter EMWIN SERVER

  15. Typical Radio Re-broadcast User 153.950KHz VHF EMWIN Up to 100 mi from transmitter line of sight Internet cloud EMWIN VHF Radio Receiver Optional Alarm Controller Internet access to Byte blaster network To Alarm Units Standard Pentium PC

  16. Internet Unicast Server EMWIN Satellite Dish Internet cloud Optional Alarm Controller Receiver Internet access to Byte blaster network To Alarm Units Standard Pentium PC

  17. EMWINTransition to GOES-N,O,P generation • Changes • Responsibilities • Prototype receiver design • Transition planning

  18. Transition to GOES-N,O,P generationChanges • Power level of broadcast must be reduced: • from 51 dBmi down to 44.8 dBmi • Frequency will change to 1692.700 MHz • Modulation will change to Offset Quadrature Phase Shift Keyed (OQPSK) • Forward Error Correction (FEC) will be utilized to compensate for reduced power • Data rate will increase to 19.2 kilobits per second (Kbps)

  19. Transition to GOES-N,O,P generationResponsibilities • NWS & NESDIS co-operative effort for development of Transition Concept • NESDIS had technical lead for developing hardware & software • Proof-of-concept prototype receiver has been built and successfully bench tested • NWS responsible for public interface and transition planning • User-vendor conferences • EMWIN web-site updates

  20. Transition to GOES-N,O,P generationPrototype Receiver Design • Hardware • Intermediate frequency (IF) adapter to convert radio frequency to audio frequency for sound card input. • Software • Demodulation and decoding accomplished by government provided software run on Windows based PC

  21. Transition to GOES-N,O,P generationPrototype schematic

  22. Transition to GOES-N,O,P generationTransitioning Planning • GOES – N launch • Has been delayed; currently scheduled for May, 2006 • Space platform checkout will take about 1 month • Field testing of prototype receiver to be done after platform checks complete • GOES – O launch: Tentatively scheduled for July 2007 • User-Vendor Conference • To be scheduled after successful receiver tests • Looking for vendors interested in designing their own version of receiver

  23. Transition to GOES-N,O,P generationTransitioning Planning – cont’d • GOES – operational • Fuel of existing GOES constellation exhausted by 2011 • Current GOES-E may run out of fuel in 2009 • No earlier phase-out of existing GOES satellites scheduled • Detailed transition plan will be posted on EMWIN web site as soon as available • Check for EMWIN updates at this location: http://iwin.nws.noaa.gov/emwin/index.htm

  24. The Third Border Initiative (TBI) • Disaster preparedness is a high priority for the United States. • Main activities are sponsored by USAID’s Office of U.S. Foreign Disaster Assistance (OFDA), U.S. Southern Command and the Third Border Initiative (TBI) through the U.S. State Department. • United States is also exploring options to use TBI funds to expand regional weather forecasting and response capabilities. • NOAA’s TBI proposal for upgrading its "hydrometeorological" network (radar, aircraft surveillance, ocean data buoys) is multi-purpose and not just for tsunamis.

  25. The Third Border Initiative cont’d • The NOAA TBI Proposal: • Would also upgrade the telecom network dedicated to sharing information on impending events, including developing a satellite-based natural hazard information network linked to the United States. • In connection with this aspect of the Proposal, NWS in consort with the NOAA International Affairs Office, is preparing a proposed pilot plan to demonstrate the installation of an EMWIN receiving station on a selected Caribbean island and train local meteorological specialists in its use.

  26. The GOES-10 Move • NOAA plans to shift the orbit of a geostationary satellite to improve coverage over South America • Continent will benefit from emerging Global Earth Observation Network • Repositioning planned for October 2006 pending the successful launch of GOES-N, NOAA's new geostationary satellite, and the continued operation of GOES-12. • Shift will help protect lives and property in North, Central and South America by significantly improving satellite detection of natural hazards. • Will further strengthen the WMO's World Weather Watch Global Observing System.
