NOAA COMMAND AND DATA ACQUISITION STATION
WCDAS Numbers
• DCS Help Desk at 757-824-7450 or 7451
• Email is [email protected] with
copies to [email protected]
• 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 Pilot 401.85
• 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
• LRIT outages continue
• Anomaly Review Board held on May 6 to discuss these issues
• 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).
• Wallops has a backup system but failovers are difficult. There
seems to be a “handshaking” issue between the two sites.
• 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 was tested and placed in storage. It
was brought out of storage in July 07 for testing.
• GOES-O launch is scheduled for December 08.
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.
GOES-11 Spring Eclipse
• GOES-11 experienced battery problems during
the Spring 08 eclipse (March).
• During the eclipse cycle (approx 2 hrs early
morning each day) services were transitioned
from GOES-11 to GOES-13
• These services were DCS, EMWIN, and LRIT
• At a minimum we plan for a EMWIN test on
GOES-13 during the upcoming eclipse.
• Far Western platforms may not be seen due to
the position of the spacecraft.
System Enhancements
• 100/300 demod upgrade allows
transmission of different rates through the
same demod
• BCH address scheme upgraded. This
gives better address correction.
• Pilot Control Module allows better receive
reference.
• Acceptance tests were run. Signoff was
April 24
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.
• 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.
GOES-12 Anomaly
• A North/South maneuver in November
resulted in an anomaly of GOES-12.
• A leak in a thruster line resulted in the
spacecraft being out of service for more
than a week.
• During this time GOES-10 was used for
DCPR
• In addition EMWIN and LRIT products were
transmitted through GOES-10
DADDS
• The DCS Alternate Data Distribution System
(DADDS) provides a separate means to
distribute data from the demods should DAPS A
& B fail.
• Training held at Wallops in Feb 08
• The system has been used on an as-needed
basis to support NWSTG and DOMSAT feeds
• Demo this week (acceptance in late July/early
August) on failover to parallel server
Multiple Data Sources
• We currently support– DOMSAT (primary)
– LRGS (cdadata, cdabackup, drot)
– Telnet (data base updates)
– LRIT
– NWS Telecommunications Gateway
– Dial-in
