  1. Proposal to add an independent GOES DCS Reception and Distribution System to complement the NESDIS Wallops Island Facility Presented by Ernest Dreyer, USGS/WRD January 23, 2008 Emergency Data Distribution Network

  2. Overview • Review EDDN project • Provide a current status

  3. EDDN Project GOALS • Receive data from all DCPs transmitting in the GOES DCS independently of Wallops Island. • Locate facility at a receive site(s) sufficiently distant from Wallops Island to achieve event independence. • Implement additional pilot signal at a location other than Wallops Island. • Distribute data independently of Wallops Island.

  4. STIWG/NESDIS Proposal • Locate the emergency distribution system at the USGS EROS Data Center in Sioux Falls, South Dakota. • USGS and NOAA/NESDIS will share the costs for procurement of the Direct Readout Ground Station system. • System will be primarily operated by USGS with support from NESDIS. • Operational costs will be shared among users who agree to participate and NESDIS.

  5. Limitations • Contains no system to • Make new assignments • Data will be acquired from any transmitting DCP and so an internal schedule will not be necessary. • Generate abnormal platform response messages - changed!!! • Messages will be checked for abnormal conditions as long as there is access to a PDT file.

  6. Limitations (cont.)‏ • Distribution will initially be over the Internet using the DDS protocol. • No DOMSAT transmissions • No direct land-lines • Depends on the existence of a usable pilot signal.

  7. Basic EDDN System • DRGS system with 2 antennas for GOES East and West ( at least 7M )‏ • DOMSAT system for data from Wallops Island • LRGS systems for acquiring and distributing data. • Web Server for reporting system status.

  8. Some Features required of theEDDN GOES Receive System • Receive both 100 and 300 baud messages on the same channel. • Support a backup pilot signal and be able to switch to the backup if the primary signal fails.

  9. Diagram of Proposed System

  10. System Monitoring • Use Big Brother system monitoring • Write Big Brother clients for monitoring • DRGSs via the DAMS NT event socket • LRGSs via system logs • Other events significant to the operations of system • Big Brother can • Display current status on web site • Send notifications to email groups • Page users

  11. System Control • After initial setup, system should operate with a minimum of operator intervention. • System will be remotely managed using a remote system console assisted by on-site support.

  12. Current Status of EDDN

  13. Calendar of Contract Events • Contract Awarded in July 2007 to Microcom Design Inc. • Contract began in Early August 2007. • Contract to be completed in February 2008.

  14. Status of EROS Installation • Antennas • GOES East: New 7.5M antenna has been installed. • GOES West: Existing 8.1M antenna has been refurbished. • DOMSAT: New 2.4M antenna has been installed. • Backup: Backup 3.8M antenna has been installed. • Cabling • All power cables have been installed. • All communications cables have been installed.

  15. Status of EROS Installation(cont)‏ • GOES Receivers • GOES Receivers are installed and receiving data from all domestic channels on GOES East and West. • To Be Done • Testing and fine tuning system will continue until final acceptance. • Operational training will occur during the last two weeks of February. • Integration into operational systems will begin in March.

  25. Status Display on EROS LRGS

  26. Status of Other Related Activities • LRGS Software • Version 6.1 of LRGS software is being tested and refined. • Public EDDN Web Server • A Web server (lrgseddn1.cr.usgs.gov) is being constructed to provide: • Status of the public LRGSs • Access to Big Brother Monitoring Page • Server Pages that • Describe the EDDN • Describe message format • Describe how to obtain and install LRGS software • Make available relevant Documentation • Accessible mirror of the LRGS software source code repository

  27. Status of Other Related Activities • User Registration • A Synchronization scheme has been established to mirror user information for users registered on the NESDIS LRGS systems. • When scheme has been implemented, users already registered with NESDIS will automatically be registered with the EDDN system. • A proposal for a new format for user Ids is under consideration. • Note: Password authentication will be enabled.

  28. Status of Other Related Activities • User Access • EDDN system can be accessed in the same manner as the current LRGSs at Wallops. • For current LRGS users, if they upgrade to version 6.1, they can configure their LRGS to include the EDDN LRGSs as dynamic backups.
