NOAA COMMAND AND DATA ACQUISITION STATION


Dcs point of contact

DCS POINT OF CONTACT

WCDA Station’s first point of contact for help is the DCS Help Desk at 757-824-7450 or 7451

Email is [email protected] with copies to [email protected]

Contact Phil Whaley at (757) 824-7331 or Al McMath at (757) 824-7316

Wallops supports 24/7 operations


Dcs configuration

DCS Configuration

  • Wallops now supports demods for two complete spacecraft (120 channels each)

  • One spare drawer on site (40 channels)

  • To date three demod failures

  • Preliminary testing has been conducted on the 100/300 baud concept (using the spare demods).


Wallops lrgs configuration

Wallops LRGS Configuration

  • The demodulators for both East and West continue to feed the LRGS directly.

  • This means that the primary LRGS (cdadata) is not dependent on DAPS. Use this as primary.

  • The receive site (drot) gets its data from the DOMSAT downlink which is heritage DAPS data.

  • We now have a third site (cdabackup).

  • Wallops supported the STWIG sub-committee considering LRGS configuration, distribution, etc.

  • 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

LRIT Status

  • LRIT traffic to Suitland is dependent on the Internet

  • Transfer of data to Suitland continues to be a “double” single point failure

  • LRIT data is returned to Wallops via T-1 lines. LRIT is an advantage to international users because DOMSAT is limited to CONUS.

  • LRIT now has full East/West data streams

  • An automatic re-transmission (one time) has been implemented.

  • 1 meter antenna receives full LRIT stream

  • There are no re-occurring costs associated with LRIT reception.


Current spacecraft status

Current Spacecraft Status

  • GOES-12 remains primary (75) for East

  • GOES-11 has been transitioned as primary West (135) spacecraft

  • GOES-10 is positioned (60) for the South American mission. Imagery operations began in Nov 06

  • GOES-9 was de-commissioned on 14 Jul 07

  • GOES-13 was tested and placed in storage. It was brought out of storage in July 07 for testing.

  • GOES-O launch is scheduled for Summer 08.


Wallops backup

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.


Domsat frequency change

DOMSAT Frequency Change

  • The final transition to the new DOMSAT frequency was June 13, 2007

  • New frequency is 11,817.5Mhz.

  • All other parameters (pointing angles, modem settings, etc.) remain the same.

  • Transition went smoothly.


Noaa command and data acquisition station

DAPS

  • Wallops has experienced data base issues (mid November). Updates had to be re-entered.

  • DAPS-B is now primary and has been since November.

  • Still supporting telnet (205.156.2.173/178)

  • Working with OSDPD in the migration to 300/1200 baud channels.

  • The Weather Service link has been transitioned to the MPLS (8 Jan 08). We are seeing fewer dropouts.

  • Wallops Operations verifies the DCS pilot daily.

  • No problems during the end-of-year transition.


Goes 12 anomaly

GOES-12 Anomaly

  • A North/South maneuver in November resulted in an anomaly of GOES-12.

  • A leak in a thruster line resulted in the spacecraft being out of service for more than a week.

  • During this time GOES-10 was used for DCPR

  • In addition EMWIN and LRIT products were transmitted through GOES-10


Dadds

DADDS

  • The DCS Alternate Data Distribution System (DADDS) provides a separate means to distribute data from the demods should DAPS A & B fail.

  • Testing was conducted at Wallops Oct 07.

  • The system has been used on an as-needed basis.

  • Currently DADDS will support NWSTG and DOMSAT traffic.

  • Training for Wallops Operations staff is scheduled for the week of 4 Feb.


Multiple data sources

Multiple Data Sources

  • We currently support-

    • DOMSAT (primary)

    • LRGS (cdadata, cdabackup, drot)

    • Telnet (data base updates)

    • LRIT

    • NWS Telecommunications Gateway

    • Dial-in
