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
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
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)
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)

The East receiver sends the LRGS an
acknowledgement of DCS file reception to close the loop on the LRGS retransmission
feature.
The filter ensures that the “harmonic
rich” modulator doesn’t interfere with other GOES
services.
LRIT is a satellite specific service

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
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.
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)
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.
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.
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.
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
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
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)
