  1. NOAA COMMAND AND DATA ACQUISITION STATION

  2. WCDAS Numbers • DCS Help Desk at 757-824-7450 or 7451 • Contact Phil Whaley at (757) 824-7331 or Al McMath at (757) 824-7316

  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

  4. Wallops LRGS Configuration • Analysis by Microcom showed that EDDN and NSOF were receiving 99.5% of the data that is received at Wallops. • No real changes to the LRGS configuration since the last meeting

  5. LRIT Status • Files built and transmitted every 30 seconds • Wallops is working with OSDPD to use the backup at Wallops during periods of outages. • The OSDPD 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.

  6. Spacecraft Constellation • GOES-10 de-commissioned in Dec 2009 • GOES-13 is prime East S/C @ 75 deg West (Apr 26) • GOES-11 is prime West S/C @ 135 deg West • We did not have to use GOES-13 for DCS/LRIT/EMWIN during recent eclipse events. • GOES-11 has only one functioning command receiver • Currently scheduled for replacement - Dec 2011 • GOES-12 supporting the South Americans @ 60 deg West • GOES-14 will be in storage @ 105 deg West  • GOES-15 will be in storage @ 89.5 deg West

  7. Wallops Backup • A second pilot remains active (channel 0) at the WBU. The frequency is 401.7MHz. • Wallops Backup has been re-positioned to support GOES-13 as the prime East S/C • LRIT and EMWIN equipment is at WBU & FCDAS still waiting for connectivity to OSDPD – multicast issue.

  8. DAPS/DADDS • DADDS on-line since Jan 2010. • IT Security Certification and Accreditation completed on Mar 31 • We now have a 3 year Authority To Operate • This includes the WCDAS and the NSOF • Three test transmitters installed, tested, and accepted during the week of Apr 26. • NWSTG TCP/IP Testing currently underway.

  9. DOMSAT Status • DCS moved from AMC 4 to SES 1 – 9 Jul • Downlink moved from transponder 6 to transponder 14 of satellite SES 1 – 1 Nov • The new frequency is 11987.2MHz. • The current contract with SES World Skies, formerly Americom Government Services (AGS), expires September 2011 (Option period-9). • Discussion with SES World Skies

  10. New DOMSAT Contract-Technical Elements- • SES was asked; if we fielded a SOW seeking a follow-on service with same XMT/RCV requirements, would they be able to support it and would they compete for it. • SES stated that they would still be able to support a follow-on service using the same interfaces & protocols. • SES stated that modems supporting this interface & low data rate should be available, at competitive prices, for the foreseeable future. • So at least one company, SES, states they could provide a follow-on service without changes to the receive sites. • Now for the "would they” part.

  11. New DOMSAT Contract -Program Elements- • SES currently has a NOAA contract for multiple DOMSAT services in the DC, Fairbanks, Wallops and other areas. This contract ends Sep 2012. • If SES wins the post-2012 DOMSAT contract, their technical and personnel support infrastructure will remain in place; this is the same support services that maintain the Wallops DCS contract. If they don't win, then their infrastructure goes away and they don't know if they'll be around to support the Wallops DCS 56kbps service. • If I put a SOW on the street today, seeking a follow-on DCS service, they would probably only support it until Sep 2012.

  12. New DOMSAT Service – Some Options • 1). Initiate a RFP towards the goal of continuing the same DCS DOMSAT service through a follow on contract: • Identify the number of years required for support. • SES may not compete & their equipment goes away. • SOW requirements for backward compatibility may = 0 proposals. • Base Period, implemented in 2001, was $57,304.00. • Annual Option Period currently $74,170.80, including NSOF backup. • 2). Seek 18 mo. extension of current contract.  Extension would allow time to see if SES would have a post 2012 infrastructure in place, and thus an interest in the DCS DOMSAT service, before generating RFP.  • Convince the Contracting Officer; lower costs, open competition, • Will still have to initiate an open RFP at some point. • 3). Let the DOMSAT service contract expire 31 Aug 2011. • Address LRIT DCS deficiencies so that there is no requirement for DOMSAT • Variations: Extend to 2012?

  13. New DOMSAT ServiceOther Considerations • Package the DCS service with the larger NOAA Service • ?
