  2. WCDAS Numbers DCS Help Desk at 757-824-7450 or 7451 Email is WCDADAPS@NOAA.GOV with copies to michael.b.galeone@noaa.gov Contact Phil Whaley at (757) 824-7331 or Al McMath at (757) 824-7316 DOMSAT frequency is 11,817.5Mhz. Still supporting telnet (205.156.2.173/178)

  3. WCDAS Numbers Wallops Pilot 401.85 Wallops Backup Pilot 401.7 MHZ

  4. Wallops LRGS Configuration • The demodulators for both East and West continue to feed the LRGS directly through the DAMS-NT. • “Test User” account has been disabled as of April 14th. • The receive site (drot) gets its data from the DOMSAT downlink which is heritage DAPS data. • We encourage cdadata as primary with drot as a troubleshooting tool. • We now have a third site (cdabackup) that mirrors cdadata. • Wallops worked with USGS to build/share LRGS account information. • Sites and IPs: • http://cdadata.wcda.noaa.gov (205.156.2.174) • http://drot.wcda.noaa.gov (205.156.2.186) • http://cdabackup.wcda.noaa.gov (205.156.2.189)

  5. LRIT Status • Complex system design and communications between sites were determined to contribute to the failures (i.e. buffering of data, computer synching problems, restarting of systems). • Transfer of data to Suitland continues to be a “double” single point failure • LRIT is an advantage to international users because DOMSAT is limited to CONUS. • LRIT now has full East/West data streams • 1 meter antenna receives full LRIT stream • There are no re-occurring costs associated with LRIT reception.

  6. Current Spacecraft Status • GOES-12 remains primary (75) for East • GOES-11 is the primary West (135) spacecraft. • GOES-10 is positioned (60) for the South American mission. Imagery operations began in Nov 06 and they continue. • GOES-9 was de-commissioned on 14 Jul 07 • GOES-13 remains out of storage for the foreseeable future. • GOES-O launch is scheduled for Spring 09.

  7. Current Spacecraft Status • GOES-13 will come out of storage on July 30 • It will remain out of storage until the end of the eclipse season (late Oct/early Nov) • GOES-13 is positioned at 105 degrees and will remain there. • While out of storage the DCS/EMWIN/LRIT transponders will be on. • GOES-O launch is scheduled for December 08.

  8. System Enhancements • Specifications for the replacement test transmitters have been generated. • Specifications for the replacement Pilot Transmit System have been generated. • Pilot Control Modules (primary and spares) have been upgraded to dual pilot capabilities, tested, and accepted at Wallops. • Wallops is procuring a DCP that will be used for testing.

  9. Wallops Backup • A second pilot remains active (channel 0) at the WBU. The frequency is 401.7MHz. • Wallops staff has remote control/status capability of the WBU systems including the pilot from Wallops.

  10. DAPS • IT team is working on the Certification and Accreditation Package. • Dial-in lines and telnet still remain as an area of concern. These services are eliminated with DADDS. • Today, still supporting telnet (205.156.2.173/178) • The Weather Service link has been transitioned to the MPLS (8 Jan 08). We are seeing fewer dropouts. • Wallops Operations verifies and reports the DCS pilot levels daily.

  11. DADDS • The DCS Alternate Data Distribution System (DADDS) provides a separate means to distribute data from the demods should DAPS A & B fail. • The system has been used on an as-needed basis to support NWSTG and DOMSAT feeds • Parallel server DADDS server was tested and accepted in Aug 08 at Wallops.

  12. Multiple Data Sources • We currently support- • DOMSAT (primary) • LRGS (cdadata, cdabackup, drot) • Telnet (data base updates) • LRIT • NWS Telecommunications Gateway • Dial-in
