  1. NOAA COMMAND AND DATA ACQUISITION STATION

  2. WCDAS Numbers • DCS Help Desk at 757-824-7450 or 7451 • 24 Hours/ 7 Days a Week • Al McMath at (757) 824-7316 • Travis Thornton 757 824-7450

  3. Wallops LRGS Configuration • No real changes to the LRGS • We continue to use version 7.0 as the standard • The cdadata server is considered the primary LRGS, ingesting data from the DCS demods & the cdabackup server. • The cdabackup server is considered the secondary LRGS, ingesting data from the DCS demods & the EDDN server. • The drot should be considered a troubleshooting tool to verify the DOMSAT downlink. • Accounts are built through NOAA and shared with USGS • Wallops LRGS interface with those at NSOF and EDDN to maintain a complete record.

  4. Wallops LRGS Configuration • No real changes to the LRGS configuration since the last meeting • 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 • Files built and transmitted every 30 seconds • Wallops is working with NSOF to use the backup at Wallops during periods of outages. • The failover would be manual – not automatic • The DCS component of LRIT is transferred from Wallops to Suitland (via Internet) and then back to Wallops (via T-1). • 1 meter antenna receives full LRIT stream • There are no re-occurring costs associated with LRIT reception. • Available throughout the hemisphere at no charge.

  6. Current Spacecraft Constellation • GOES-13 is Prime East S/C @ 75 deg West • GOES-11 is Prime West S/C @ 135 deg West. • Only one functioning command receiver • Currently scheduled for replacement - Dec 2011 • Scheduled replacement is G15 • GOES-12 is Prime South Americans @ 60 deg West • GOES-12 is scheduled for de-commissioning in Dec 2013 • No decision on supporting South America after Dec 2013 • GOES-14 is in storage @ 104 deg West • We are using the SXI instrument   • GOES-15 is in storage @ 89.5 deg West

  7. GOES West Scheduled Transition • Currently - GOES-15 is in storage @ 89.5 deg West • Oct - G15 begins westward drift from 89.5W to 135W • Rate is <1deg/day • Dec 6 – G15 nears 129 W • Sensor Data Link (SDL) transitions to GOES G15. • G15 Processed Data Relay (PDR) transmitted through G11 • Ground PDR antennas don’t have to repoint • G15 continues to drift westward • Dec 14 – G15 drift stops at 135W. • All G11 service links transition to G15 • Dec – G11decommision and de-orbit.

  8. DAPS/DADDS • Demods upgraded to be CS2 Compatible. • No longer supports long inter-leaver messages. • DAMS-NT Interface updated for msec time resolution (V8) • Upgrade Task underway for CS1/CS2 Auto-detect. • Initial deployment of Test Channels. • NWSTG TCP/IP testing currently underway. The X.25 stream is expected to be terminated sometime within the next few weeks.

  9. DAPS/DADDS • Pilot/DCPC receive antennas installation was pushed into new fiscal year 2012. • A second pilot remains active (channel 0) at the WBU. The frequency is 401.7MHz.

  10. GOES East • 300bps • 195E for CS1 & CS2 (401.99200 MHz) • 1200bps • A99 for CS1, 497 for CS2 (401.99575 MHz) • Incompatible with CS2-needs to move • 100/300 bps Auto Detect • 151E CS1 Only (401.9260 MHz) • GOES West • 300bps • 196W for CS1 & CS2 (401.99350 MHz) • 1200bps • A100 for CS1, 499 for CS2 (401.99875 MHz) • 100/300 bps Auto Detect • 151E CS1 Only (401.9260 MHz) Test Channels

  11. DOMSAT “Old Business” • The 10 year contract with SES World Skies, formerly Americom Government Services (AGS), formerly GE Americom, formerly General Electric American Communications, Inc. expired 31 August 2011. • Total Cost of 10 year service was $650,010.80 • Includes $101,963 for 2008 NSOF Backup ($77,316 installation)

  12. DOMSAT “New Business” • New DOMSAT Contract in place September 2011 • Provides for a maximum of 16 months service • 7 months funded Base Period • 1 September 2011 – 31 March 2012 • 6 month Option Period • 1 April 2012 – 30 September 2012 • 3 one month Option Periods • 1 October 2012 – 31 December 2012 • It is the expectation that the DCS DOMSAT service will be combined with a larger NOAA DOMSAT service contract, award date expect 5 September 2012

  14. DOMSAT Service

  15. DOMSAT Service • SES has proposed updating the Wallops ground system equipment, in Dec-Jan. • Replace 2.4m & 1.8m antenna equipment • SES has also indicated that they will need to switch satellite transponder services. • Same satellite - SES 1 • Different Frequency • December-January

  16. DOMSAT Link • DCS DOMSAT Circuit# 8819 • Service moved from AMC 4 to SES 1 – 9 Jul 2010 • Service again moved from transponder 6 to transponder 14 of satellite SES 1 – 1 Nov 2010 • Current Satellite, SES-1 • Located at 101deg West • Ku Transponder 14 • 11987.2MHz • Horizontal Polarization
