Wallops LRGS Configuration • The demodulators for both East and West continue to feed the LRGS directly through the DAMS-NT. • 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. • LRGS version 7.0 has become the standard and all Wallops LRGS have been updated (drot and cdabackup updated in the last month). • Accounts are built through NOAA and shared with USGS • 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)
Wallops LRGS Configuration • Recent (Oct 09) updates to the LRGS/LRIT applications provided: • Wallops with the ability to simultaneously stream the DCS data to the NSOF primary, backup, and the OSDPD Backup Facility (OBF) LRIT servers • Provided Wallops with enhanced troubleshooting tools to monitor the LRIT delivery of the three streams
LRIT Status • The OSDPD has acceptance tested new Domain servers that should resolve Domain data transfer problems to Wallops. • The new systems are currently being integrated • The DCS component of LRIT is transferred from Wallops to Suitland (via Internet) and then back to Wallops (via T-1). • Occasionally , during a planned outage Wallops will simu-cast a single stream to both East and West (this keeps DCS up). • LRIT is an advantage to international users because DOMSAT is limited to CONUS. • 1 meter antenna receives full LRIT stream • There are no re-occurring costs associated with LRIT reception.
Spacecraft Status • GOES-10 is scheduled for decommission on Dec 1, 2009 (1230Z – 7:30am) • Still awaiting NOAA administrator for signoff on GOES-10 decommission (approved by NESDIS). • GOES-12 currently primary (75W) for East • GOES-12 will support South American mission in May ‘10. Fuel available for 3 years coverage. This allows for East-West not North-South mnvrs.
Spacecraft Status • GOES-13 remains in storage – but not for long • GOES-13 will replace GOES-12 as the primary East spacecraft in April 2010 • GOES-13 becomes East S/C at 81W and continues drift to 75W. • No reposition of DCP antennae required.
Spacecraft Status • GOES-11 is the primary West (135W) spacecraft and it will remain so. • GOES-14 is positioned (105W) and will remain active to support the XRS instrument • Batteries on GOES-11 look OK. We did not have to use GOES-13 for DCS/LRIT/EMWIN during Fall eclipse. • GOES-P (GOES-15) launch is scheduled for March 10, 2010 • Post Launch Testing at Wallops during the Spring of 2010
Spacecraft Constellation • GOES-13 will be prime East (Apr 2010) • GOES-11 will be prime West • GOES-12 will support the South Americans (May 2010) • GOES-14 will be in “storage” but still support XRS (X-Ray Sensor) • GOES-13 will be first spacecraft to support 750Hz channelization (function of S/C power) • GOES-P/15 will be placed in storage due to 5 warranty of instruments. No plans to activate S/C at this point.
Certification • 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 staff has remote control/status capability of the WBU systems including the pilot from Wallops. • LRIT and EMWIN equipment is at WBU & FCDAS still waiting for connectivity to OSDPD – multicast issue.
DAPS • IT team is working security –later slide • Dial-in lines were terminated in June 2009. A few calls but no serious issues in transitioning users. • Dial-in users have been transitioned to the LRGS. • Telnet discontinued on Oct 5, 2009 • All DOMSAT and Weather Service dissemination is through DADDS • Wallops Operations verifies and reports the DCS pilot levels daily.
DOMSAT • Sep 1, 2009 to Aug 31, 2010 began Option Period-8 • The current contract with Americom Government Services (AGS) expires September 2011. • 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)
DCS - Security • Certification and Accreditation efforts began on Oct 1. • Boundaries include Wallops and NSOF • C&A package due Mar 2010 (wanted 60 days in adv) • Most of DADDS security H/W in place • HTTPS on Wallops systems is now in place
DADDS • The transition to the DCS Alternate Data Distribution System (DADDS) began on Oct 5, 2009 • DAPS –B continues to ingest data but the database is drifting. • OSD has been provided requirements to transition to DADDS full time • The system is being used to support NWSTG and DOMSAT feeds full time • GOES Incident Reports are being written • Test Transmitter delivery expected in Nov. • Addition software by the end of the year.
