NOAA COMMAND AND DATA ACQUISITION STATION

1. NOAA COMMAND AND DATA ACQUISITION STATION

3. 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

4. Wallops LRGS Configuration • No real changes to the LRGS • We continue to use version 7.0 as the standard • The cdadata server is consider the primary LRGS • The cdabackup server is considered the secondary LRGS which mirrors EDDN • The drot should be considered a troubleshooting tool to verify the DOMSAT downlink. • Wallops with the ability to simultaneously stream the DCS data to the NSOF primary, backup, and the OSDPD Backup Facility (OBF) LRIT servers (Oct 09) • Accounts are built through NOAA and shared with USGS

5. 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 • 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)

6. 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 fix for the “flooding” issue has been installed and is working properly. • 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. • LRIT issues in Mar 10 • Mar 19 – 22 replication down due to account problems • Mar 24 - Five minute outage due to socket problems • Mar 26 - four hour outage due to T-1 failure • Mar 28 - five hour outage due to T-1 failure (Verizon frame problem)

10. Spacecraft Status • GOES-11 is the primary West (135W) spacecraft and it will remain so. • Batteries on GOES-11 look OK. We did not have to use GOES-13 for DCS/LRIT/EMWIN during Spring eclipse. • However, GOES-11 has only one command receiver that is functional • GOES-14 is positioned (105W) and will remain active to support the XRS instrument

11. Spacecraft Status • GOES-P (GOES-15) was launched successfully on March 4, 2010 • Post Launch Testing successfully completed at Wallops during the Spring of 2010 • GOES-P/15 will be placed in storage due to 5 year warranty of the instruments. No plans to activate S/C at this point.

12. Spacecraft Constellation • GOES-10 was de-commissioned in Dec 2009 • GOES-13 is now prime East S/C (as of Apr 26) • GOES-13 will be first spacecraft to support 750Hz channelization (function of S/C power) • GOES-11 remains prime West S/C • GOES-12 started its drift (27 Apr) to support the South Americans (May 2010) • GOES-14 will be in “storage” but still support XRS (X-Ray Sensor) • GOES-15 will be in storage (T&C only)

13. Certification • October’s slide Phil needs to speak to this one • Version 2 (channel splitting & tighter receive filtering) of Cert Standards ratified by OSD in Oct 2009 • Three certification test sets to support the new standards have been upgraded and are being deployed to vendors upon request • It is not expected that 100bps will not be supported for certification after ver 2 standards are adopted (this is policy, only 4 years left on 100bps support). • It has been proposed that the Wallops 300 & 1200bps test channels, for East and West, be upgraded to be compliant with the ver 2 certification standard.

14. 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.

15. DAPS/DADDS • IT team is working security –later slide • DADDS on-line as the primary DCS processing system in Jan 2010 • Transition began on Oct 5 DAPS/DADDS operations were in parallel until Jan. • All services are now through DADDS • Three test transmitters installed, tested, and accepted during the week of Apr 26. • Three pilot transmitters installed, tested, and accepted during the week of Apr 26. • Wallops Operations verifies and reports the DCS pilot levels daily.

16. DADDS • A complete backup resides at NSOF. This includes the RF front end (demods) and the associated demodulators. • GOES Incident Reports have been generated • Software release 3.051.5 in Apr 2010 addressed many of these issues

17. DCS - Security • Certification and Accreditation efforts began on Oct 1. • C&A was completed on Mar 31 • We now have a 3 year Authority To Operate • This includes the WCDAS and the NSOF • Boundaries include Wallops and NSOF • All of DADDS security H/W in place • HTTPS on Wallops and the NSOF systems is now in place

18. DOMSAT • Aug 31, 2010 marks the end of Option Period-8 • The current contract with Americom Government Services (AGS) expires September 2011 (Option period-9 the final option). • Wallops in discussion with DOMSAT provider to identify modem options for consideration in follow-on DOMSAT contract discussions (x25 and 56k bandwidth may not be practical after FY12)
