This Summer and Fall

• GOES-12 remains primary (75) for East
• GOES-11 transition as primary West (135) as of
  6/28/2006. There was a minimal loss of 7 minutes
  of WEST DCS data during the event.
• GOES-10 still moving (60) for the South American
  mission. GVAR on-line 18 Nov.
• GOES13 Successful launch in May, PTL testing was
  performed over the summer months. Goes into
  storage for two years on 27 Dec 06.
• The GOES EAST operations will utilize either
  GOES-10 or 13 in the event of a GOES-12 failure.

New OSDPD Building

• The purpose of the OSDPD is To ensure that
  critical ops continueat NOAAs NESDIS and the
  Environmental Satellite Processing Center.
• Wallops is awaiting notification for the systems
  delivery and installation date.
• Will cover ALL OSDPD products to include Polar,
  International, and GOES (EMWIN, LRIT, SatSat,
  GINI, etc.)

Wallops Backup

• EMWIN and LRIT equipment has been installed at
  the WBU (also FCDAS)
• A second pilot is active (channel 0) at the WBU
• Mission failovers to GOES-10/11/12 (WBU) and
  GOES-10/11 (FCAS) have been successful as
  validation of the COOP.
• Wallops staff can now remotely control the WBU
  systems from Wallops

DEMODULATORS

• Final phase for the DSP DAMS-NT demods have been
  installed for GOES-East and West DCS subsystem.
• Currently DCS has 120 DAMS-NT each for both East
  and West DCPR, not including spares . The system
  no longer has the legacy Telcom or Vitel units.
• In Sept. the DSP demods were networked to the
  LRGS system. The user community has real-time
  data access via to the LRGS system.
• This translates into a direct feed from the
  demods to the LRGS for Internet users therefore,
  we are bypassing the DOMSAT feed from DAPS to
  populate the LRGS.
• This gives Wallops an on-site backup for Internet
  traffic that is removed from the heritage DAPS.

LRIT

• Transfer of data to Suitland continues to be a
  double single point failure
• LRIT is dependent on the Internet
• LRIT can be received directly off the GOES
  spacecraft, eliminating the need for DOMSAT which
  only see the CONUS.
• Flooding of the LRIT messages was corrected with
  the separation of the DOMSAT (the direct feed to
  the LRGS) and a software upgrade.
• Wallops has implemented a quality monitoring
  system that compares LRIT messages sent from DCS
  to those received on the LRIT downlink. If a
  message fails to make it through the system there
  is one re-transmission from the LRIT source
  system.
• To address DCS LRIT COOP vendor contacted to
  inject DCS into LRIT stream at WCDAS, WBU, and
  FCDAS

14
DAPS

• In Sept. had a failure with the Nokia checkpoint
  firewall. It was replace with a new Cisco ASA
  5510 firewall. Prepared new firewall with user
  names and new passwords. WCDA is planning on a
  Dec. 4th transition.
• Numerous problems with DOMSAT and
  retransmissions. New procedure was released and
  link was separated from DAPS-1. DCS data is
  networked to the LRGS directly from the DAMS-NT
  units.
• Experienced some truncated/parity problems with
  some messages. Fix was antenna alignment and
  pilot power adjustment. New procedure for
  technicians was released.
• The DCS network is on its own separate LAN
• Since the last TWG new servers for CDADATA, DROT,
  CDABACKUP (DROT1), Webpage were installed.

DCS FIREWALL ACCESS

• For added security and reliability the DCS
  Technicians will add a strong authentication
  process to DAPS.
• This will occur during the 1st week of Dec 2006.
• Prior to this event, the users should call the
  DCS help desk to inquire about their password.
  The password will be unique per user and assigned
  by the DCS Technicians. 757-824-7450 or 7451.
• The login process will change, in that the
  firewall will start authenticating users, and the
  users will need to login to the firewall using
  their existing DCS username and the assigned
  strong password. You will not be able to change
  it, and if forgotten, you will be required to
  call in to the DCS Technicians to receive it.
• Upon a successful login to the firewall, you will
  need to login to DCS using your existing DCS
  credentials, those will not change.

17
LRGS

• As of Sept 2006 the DAMS-NT demodulators data is
  fed directly to the LRGS servers.
• The LRGS and LRIT software live on the same
  server. There is a full backup on line at
  Wallops. The IP addresses are CDADATA -
  205.156.2.174 and CDA_BACKUP -205.156.2.189
• This configuration avoids any duplication of
  DOMSAT messages.

DAPS-II

• The Government has settled the ISI claim
• With the approval of OSPD, DAPS-II equipment has
  been distributed to other areas to support the
  GOES mission.

DCPI

• NTIA is waiting for NOAA to provide GOES-N
  frequency filing information
• Technical specifics on the DCPI transmitters
• Measured performance values of the DCPI
  transmitters
• During the summer WCDAS personnel met with NOS
  and Sutron to discuss plan of using DCPI link
  with CDMA transmission format.
