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)

WCDAS Numbers

• Wallops Backup Pilot 401.7 MHZ

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)

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.

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.

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.

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.

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.

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.

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.

Multiple Data Sources

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