  1. NOAA COMMAND AND DATA ACQUISITION STATION

  2. DCS POINT OF CONTACT WCDA Station’s first point of contact for help is the 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 Wallops supports 24/7 operations

  3. DCS Configuration • Wallops now supports demods for two complete spacecraft (120 channels each) • One spare drawer on site (40 channels) • To date three demod failures • Preliminary testing has been conducted on the 100/300 baud concept (using the spare demods).

  4. Wallops LRGS Configuration • The demodulators for both East and West continue to feed the LRGS directly. • This means that the primary LRGS (cdadata) is not dependent on DAPS. Use this as primary. • The receive site (drot) gets its data from the DOMSAT downlink which is heritage DAPS data. • We now have a third site (cdabackup). • Wallops supported the STWIG sub-committee considering LRGS configuration, distribution, etc. • 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 • LRIT traffic to Suitland is dependent on the Internet • Transfer of data to Suitland continues to be a “double” single point failure • LRIT data is returned to Wallops via T-1 lines. LRIT is an advantage to international users because DOMSAT is limited to CONUS. • LRIT now has full East/West data streams • An automatic re-transmission (one time) has been implemented. • 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 has been transitioned as primary West (135) spacecraft • GOES-10 is positioned (60) for the South American mission. Imagery operations began in Nov 06 • 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 Summer 08.

  7. 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.

  8. DOMSAT Frequency Change • The final transition to the new DOMSAT frequency was June 13, 2007 • New frequency is 11,817.5Mhz. • All other parameters (pointing angles, modem settings, etc.) remain the same. • Transition went smoothly.

  9. DAPS • Wallops has experienced data base issues (mid November). Updates had to be re-entered. • DAPS-B is now primary and has been since November. • Still supporting telnet (205.156.2.173/178) • Working with OSDPD in the migration to 300/1200 baud channels. • The Weather Service link has been transitioned to the MPLS (8 Jan 08). We are seeing fewer dropouts. • Wallops Operations verifies the DCS pilot daily. • No problems during the end-of-year transition.

  10. 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

  11. DADDS • The DCS Alternate Data Distribution System (DADDS) provides a separate means to distribute data from the demods should DAPS A & B fail. • Testing was conducted at Wallops Oct 07. • The system has been used on an as-needed basis. • Currently DADDS will support NWSTG and DOMSAT traffic. • Training for Wallops Operations staff is scheduled for the week of 4 Feb.

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